I admit I'm overly obsessed with my upcoming trip and did my daily check of my outbound flight which is on delta. Well my flight from cmh to lax changed from 730a to 700a and when I looked it showed no flight from lax to las. I quickly called delta and the agent looked it up and the flight from lax to las had a change in not only departure times but flight numbers. Instead of getting into Vegas at 1115a I now have a 1050a arrival. And since I had a premium seat upgrade bought I insisted on getting it on the "new flight" which they quickly did. Is this normal service with delta, to make changes and not let the passenger know? My return is on southwest, although it's a 6am flight I can't complain. Iv never left Vegas so early but it was free vas now the same flight and the test that day are over $300 and the day I booked it it was$199 cash price.
