The Delta airline ticket kiosks were apparently designed and built by students from year 1 CS using Visual Basic. I guess that it is the case, based on the fact that apparently never heard when someone sells something, is bad form to take their money and not deliver the product. They do not know that such transaction processes must adjust to ensure that they are atomic. Someone should give them a clue.
Last Friday on our way home from San Jose, Steve and I had the opportunity to get on a previous flight for $50. I was checking both us in so it came to me in my credit card for the fee of $100. The kiosk says "sorry, we cannot read your card." "Please try again." I did so. Card error the second time, by which try to Steve card. The machine not as Steve card well and after displaying the same message, print our original tickets and sent us in the form. We went to the counter and bought the upgrade.
This morning, Steve was looking on the Bill of credit card and, surprise!, three failed upgrade purchases were charged to our cards, although the team said that the letters were unreadable and not deliver the previous flight.
I could forgive a small startup to do transactions on right, but Delta must have some people who have heard of them, understand their importance and can be obtained right kiosk software. Perhaps I am too much credit. I can not imagine a large company in 2011 which has problems with transactional integrity in simple purchases. I've always assumed they would get this far right. It should perhaps begin to question his ability to fly safely as well as a plane.
