Two things I was not happy about. I thought when we upgraded from the basic ticket we got one free checked bag, we did not. Also I'm a United Premier member so I was under the impression I would get my priority 2 boarding status, we did not and lastly, I paid and have TSA precheck and do not understand why that was not applied to my ticket. Delta honors all their members benifits and board's veterans. For boarding. No cost to the airlines, just common courtesy and respect for ones service to their country.
