Get random error "communication was not successful", makes me put in the same information 3 times, despite being on a reliable connection. Tries to communicate aggressively with known tracking and data mining servers, and refuses to work on a network with restrictions connecting to said servers, despite being not reliant on them for core functionality. Bad app that is required for travel, will uninstall ASAP.

- Keeps stooping to new lows. You would think they'd tie the paid seat of a 5yr old to that of the parent and note that in their system...but nope. - They don't tell you their arrival terminal is moving 2miles out. - Nor that the seat you reserved and paid the full price for DOES NOT RECLINE AT ALL -and that on a 14.5hr flight.
