Abstract: Disclosed are a message sending method and apparatus. The method includes: a front-end device receiving a message preview instruction and sending the message preview instruction to a server; the server determining, on the basis of the message preview instruction, whether a message currently corresponding to a message type satisfies a sending rule, and if so, making an electronic message correspond to the message type, and sending the electronic message to the front-end device; the front-end device outputting and displaying the electronic message for a user to view; and the user triggering a message sending instruction after confirming same, so as to complete the sending of the electronic message.

Abstract: A port departure service processing method, apparatus and system. The method includes: determining the current master control system for executing a port departure service; during the process of executing the port departure service, if an error is detected in operating data of the current master control system, switching the unfinished port departure service to another normally operating system so as to continue execution; if the execution of the port departure service is not completed and after it is detected that the operating data of the current master control system returns to normal, switching to the current master control system to continue to execute the remaining port departure service; and after switching from the current master control system to the other system or switching from the other system back to the current master control system, correcting inconsistent data before and after switching.

Abstract: An air freight rate data caching method and system. The method includes converting air freight rate data into a data format of a first-level cache, and storing same in the first-level cache; performing, on the basis of a flight origin city and a flight destination city, data fragmentation on the air freight rate data stored in the first-level cache so as to generate fragmented data; and storing the fragmented data, after same is validated, in a second-level cache. Each data node of the fragmented data cached in the second-level cache only includes part of the air freight rate data on which a fragmentation algorithm can be performed, and therefore, the horizontal expansion capacity of a cache system is improved relative to the case where cached data copies are all complete sets.

Abstract: A virtual payment method and system. A first virtual account is associated with a physical account, and a second virtual account is associated with the physical account. That is, virtual accounts of different accounts are all associated with the physical account. During the payment for flight ticket booking information by means of virtual payment, it is an exchange of a virtual currency between different virtual accounts associated with the same physical account. During the process, balances in virtual accounts that exchange virtual currencies with each other change, but the total amount in the physical account associated with a plurality of different virtual accounts remains unchanged, that is, the actual currency amount in the physical account does not change. The present invention would not he restricted by an implementation measure of the Central Bank.

Abstract: A resource allocation method and apparatus for flight cabin seats. The method includes: acquiring preset startup information and passenger name record PNR information of a target flight; determining a target flight segment according to a preset flight segment priority; comparing sold cabin seat information with saleable cabin seat information of the changed aircraft type, to determine an overflow state of the target flight segment; if the target flight segment is in a state where a flight is not overloaded and a cabin is overloaded, determining overflowed passengers according to a single-cabin overflowed people quantity and a passenger check-in state of an overloaded main cabin; and allocating target cabin seats to the overflowed passengers according to a preset cabin seat mapping rule.

Abstract: A tracing-based passenger protection method and apparatus, and a check-in system. The method and the apparatus specifically relate to: determining, according to message information included in a received message, whether tracing-based protection is required; when it is determined that tracing-based protection is required, further determining whether a passenger has been subjected to class upgrade or downgrade; and if the passenger has been subjected to class downgrade or upgrade, outputting tracing-based protection scheme information, wherein the tracing-based protection scheme information comprises class upgrade tracing-based protection scheme information of a passenger who has been subjected to class downgrade and class downgrade tracing-based protection scheme information of a passenger who has been subjected to class upgrade.

Abstract: A validation adjustment method and apparatus for flight validation batches.
