Delta ???
You're going to ride on Delta Airlines ? Why would you wonder what to expect ? It's an airplane ride. Get on board, keep your feet off the furniture, don't give the F/A's any crap, don't be drunk ( I threw many people off the airplane in my 30+ years as a Delta pilot...you cannot be on board if you even "appear to be intoxicated"...FAR's ). It's just like being on any other airline.
