Description

Technical Field

[0001] The present application belongs to the technical field of airline ticket services, and in particular, relates to a method, device and electronic device for displaying tiered refund and change rules. Background Art

[0002] In the field of modern air transportation, the refund and change rules of air tickets are an important guide for passengers to adjust their itineraries. The emergence of the tiered refund and change rules for air tickets has built a fairer and more reasonable bridge between passengers and airlines.

[0003] The complexity and diversity of refund and change policies are the inevitable result of the continuous development of the aviation transportation industry and its adaptation to market changes. As market demand continues to evolve, passengers' travel plans have become more diverse and uncertain. Some people may need to change their itineraries due to emergencies, while others may find a more suitable travel time or flight after purchasing their tickets. In this case, the requirements for refund and change are becoming more and more sophisticated. There is no longer a single unified regulation for refund and change, but a more sophisticated refund and change gradient has been established.

[0004] The tiered refund and change rules for air tickets are divided into different refund and change levels according to different situations to achieve more accurate management and service. This gradient setting takes into account many factors, including ticket purchase time, flight departure time, cabin class, etc.

[0005] First, the time of ticket purchase has become one of the important bases for dividing the tiers. If passengers buy tickets long before the flight takes off, the flexibility of refund and change is relatively high. This is because buying tickets in advance gives airlines more time to allocate capacity and has less impact on flight operations. For example, passengers who buy tickets several months in advance may only need to pay a lower proportion of handling fees when canceling and changing, and may even be able to cancel and change for free within a certain period. Secondly, the flight departure time is also closely related to refund and change. The closer the flight departure time is, the more restrictions there are on refund and change, and the higher the cost. For example, if you change your flight within 72 hours before the flight takes off, you may have to pay a high change fee. In addition, the cabin class is also an important factor affecting the refund and change policy. High-end cabins such as business class and first class often have more flexible refund and change rights. This is because passengers who buy high-end cabins are often less sensitive to prices and pay more attention to the comfort and flexibility of travel. In economy class, the refund and change conditions and fees of different sub-cabins are also different. Generally speaking, the refund and change policies for lower-priced sub-class tickets are relatively strict, while those for higher-priced sub-class tickets are relatively loose.

[0006] The refined refund and change gradient setting has brought many benefits to airlines and passengers. For airlines, it can more effectively balance operating costs and passenger needs, improve the utilization rate of flight resources, enhance service quality, and enhance market competitiveness. For passengers, it gives more opportunities to choose suitable tickets according to their own conditions. It makes the refund and change fees more transparent and reasonable. Passengers can clearly understand the costs required for refund and change according to their ticket purchase time and cabin class, so as to better plan their itinerary and make travel more convenient and safe.

[0007] However, in actual operation, when passengers purchase tickets, how to clearly display the refund and change rules for different time periods and cabin classes, ensure the effective implementation of the tiered refund and change rules for air tickets, and avoid disputes caused by unclear information has become an issue that the industry urgently needs to solve.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0061] As used herein, the term “including” and its variations are open inclusions, ie, “including but not limited to”; the term “based on” means “based at least in part on”; and the term “one embodiment” means “at least one embodiment”.

[0062] It should be noted that the modifications of "one" and "plurality" mentioned in the present application are illustrative rather than restrictive, and those skilled in the art should understand that unless the context clearly indicates otherwise, it should be understood as "one or more".

[0063] Explanation of terms

[0064] Freight: The cost of using a certain means of transportation to transfer passengers, cargo, and mail from point A to point B. Civil aviation freight includes air ticket prices, taxes, and additional service fees.

[0065] One-way: refers to traveling in one direction from the origin to the destination without returning to the origin; including direct travel between two points or travel between multiple points, such as Beijing-Hong Kong.

[0066] Round trip: refers to a trip where the origin and destination are the same place, all by air, with no ground segment, divided into outbound and return trips, such as Beijing-Hong Kong-Beijing.

[0067] Gap leg: ground transport segment, which can be divided into three situations: gap at the origin, OOJ (such as Beijing-Hong Kong / Hong Kong-Tianjin); gap at the turning point, TOJ (such as Beijing-Hong Kong / Macao-Beijing); gap at both ends, DOJ (such as Beijing-Hong Kong / Macao-Tianjin).

[0068] Price search system: It is used in the price inquiry process of passengers when purchasing air tickets. It provides price search services based on the available seats on flights for domestic airlines and agent customers, and provides an interface for customers' e-commerce sales platforms.

[0069] Refund and Change Rules: Refund rules and change rules information.

[0070] Figure 1 The operation flow of the air ticket price search system provided in the embodiment of the present application is shown, including the following steps:

[0071] Flight construction: First, build a path based on the departure and arrival cities entered by the user. Then, based on the constructed path, search for flights for each segment of the path, obtain flight and cabin information, build a flight route, and configure cabin information for each flight.

[0072] Itinerary splitting: split the user's actual itinerary into one or more fare combination plans. The fare combination plan is the minimum calculation unit for fare search and can be used to attach fare information and flight information. The created fare combination can be divided into one-way full-trip fare, one-way multi-segment fare, round-trip full-trip fare, and round-trip multi-segment fare.

[0073] Get freight rates: Get freight rate data based on the freight rate combination plan.

[0074] Freight rate verification: including space verification, authority verification, rule verification, route verification, etc. Through these verifications, it can be ensured that the itinerary solution is accurate and meets the conditions. Only itinerary solutions that pass the freight rate verification can be returned.

[0075] Freight Calculation: Process the calculation results of the freight combination plan item by item, combine the freight prices in each itinerary plan, and generate the itinerary plan price result.

[0076] Generation result: After the combined verification and calculation of the fare, the information specified in the user input message is processed and displayed. The displayed information includes: flight information, corresponding fare of the flight, and tiered refund and change rules.

[0077] Figure 2 The following is an example of a page where an airline enters fare binding refund and change rules in an embodiment of the present application, such as Figure 2 As shown, the airline enters the fare through the front end. When publishing the rule data in the fare data, it binds the change rules and refund rules. The rule data entered at this time includes the tiered refund and change rules set by the airline according to its own needs.

[0078] The data is pushed to the freight rate backend database, and the corresponding data tables include: refund rule main table, change rule main table, refund rule details table, change rule details table. In subsequent logic processing, these tables will be called separately to perform rule verification.

[0079] Figure 3 The figure shows the overall implementation process of the method for displaying the step-by-step refund and change rules provided in the embodiment of the present application. Figure 4 The operational architecture of this method is shown.

[0080] like Figure 3 and Figure 4 As shown, the method comprises the following steps:

[0081] In the main process of the air ticket fare search system, between the fare calculation and result generation stages, the refund and change rule acquisition logic is executed, which is divided into the refund rule acquisition process and the change rule acquisition process. Depending on whether the tiered refund and change rules need to be displayed in the user's request, it is decided whether to call the refund and change rule acquisition process. The following describes the refund rule acquisition process and the change rule acquisition process respectively:

[0082] (I) Obtaining the refund rules and procedures

[0083] (1) First, determine whether the rule ID corresponding to a certain fare can be found in the refund rule master table. If the refund rule record can be found, continue to search the corresponding refund rule detail table through the rule ID of the refund rule record in the refund rule master table.

[0084] (2) Following the previous step, if the refund rule record corresponding to the record can be found in the refund rule table, a single check is performed on each of the refund rule records found, including the fare basis, booking class, ticket status, peak and off-peak seasons, and other fields.

[0085] (3) If the refund rule record in the previous step passes the verification, the refund rule result that passes the verification is returned for the subsequent integration result display. The rule record that fails the verification is displayed as verification failure.

[0086] (II) Obtaining the change rule process

[0087] (1) First, determine whether the rule ID corresponding to a certain freight rate can be found in the change rule master table. If the change rule record can be found, continue to search the corresponding change rule detail table through the rule ID of the change rule record in the change rule master table.

[0088] (2) Following the previous step, if the change details record corresponding to the record can be found in the change rule details table, a single check is performed on each of the change details records found, including the fare basis, booking class, ticket status, peak and off-peak season, etc.

[0089] (3) If the change rule record verification in the previous step passes, the change rule result that passed the verification will be returned for the subsequent integration result display. The change rule record that failed the verification will be displayed as verification failure.

[0090] (III) After receiving the refund or change rules, the main operation process of the air ticket fare search system integrates the contents of these rules in the result generation stage and finally returns them to the user.

[0091] In order to better understand the technical solution of the present application, it is further described with reference to the following embodiments.

[0092] User Requests and Settings

[0093] like Figure 5 As shown, the "Whether the result requires tiered refund and change information" field is set in the request for the user to fill in.

[0094] isRefundReissueRuleNeeded = Y, indicating that the user needs to query the tiered refund and change information. The fare search process queries the table related to the refund and change rules and obtains the refund and change rule information;

[0095] isRefundReissueRuleNeeded = N, indicating that the user does not need to query the tiered refund and change information.

[0096] (1) In the fare search result message, the fare Fc item is associated with the tiered refund and change rule number, which is represented by the RefundDetailRph and ReissueDetailRph fields, such as Figure 6 As shown:

[0097] Whether to display is conditional:

[0098] The rule is only bound to the refund rule and only displays RefundDetailRph;

[0099] The rule is only bound to the change rule and only displays ReissueDetailRph;

[0100] The refund and change rules are bound together, and both RefundDetailRph and ReissueDetailRph are displayed.

[0101] Through the above rule number, the two nodes FsRefundRuleDisplay and FsReissueRuleDisplay are associated to display the details of the step refund rule and the step change rule respectively. Figure 7 As shown:

[0102] Whether to display is conditional:

[0103] The rule is only bound to the refund rule and only displays FsRefundRuleDisplay;

[0104] The rule is only bound to the change rule and only displays FsReissueRuleDisplay;

[0105] The refund and change rules are bound together and displayed in FsRefundRuleDisplay and FsReissueRuleDisplay.

[0106] (2) The information that can be displayed under the tiered refund rules includes: refund fee percentage based on the time before or after flight departure, passenger type, flight type, ticket usage, frequent flyer level, etc. Figure 8 The following is a description of the specific contents returned by the refund rules.

[0107] (3) The information that can be displayed under the step-change rules includes: the change fee percentage based on the time before or after the flight departure, passenger type, flight type, ticket usage, frequent flyer level, etc. Fig. 9 The following table shows the specific content description returned by the change rule.

[0108] Fig.10 The present invention shows a device for displaying the tiered refund and change rules, including:
