The invention discloses a method for calculating the comfort degree of a flight. The method comprises the following scoring indexes: departure average delay time scoring, arrival average delay time scoring, departure relying-on-bridge rate scoring, airplane type scoring, airplane age scoring, airplane seat pitch scoring, airplane seat width scoring, airplane seat tilt scoring, on-board recreational facility equipping scoring, on-board WIFI (Wireless Fidelity) equipping scoring, on-board power supply equipping scoring, on-board meal preparation scoring, airline service attitude scoring and the service index scoring of departure and destination airports; and the practical comfort degree index score of the flight is the sum of the above index scoring. By use of the method, a more scientific product classification way is provided for on-line travel agencies and airlines, product advantages are differentiated, and the ticket sales volume of the on-line travel agencies and the airlines are directly accelerated. For passengers, the comfort degree of the flight can be more scientifically calculated, and a third flight selection reference data index, besides flight moments and flight price, is provided for the passengers.
