So Delta calls me to the desk to verify my passport. No big deal. But they already verified my passport on the outbound trip. They verify again on boarding. They verified at security on the front end and UK on entering last week and in Switzerland when exiting. They verify at immigration.
Further, when you buy the tix you enter the number, but to print your own boarding pass you have to do it again, each time (going and coming).
Can't the system remember this data?
How does this multiple inspection of the same document make anyone more secure?
