Thank you everyone for the replies. I am going to make some phone calls tomorrow. I just realized that according to the delta site. You must be at the gate 45 min before check in to fly, and if my flight from asheville is on time. I will have only 46 minutes, so I will have one minute from my gate to the departing gate to make it on time.
Many airports will not take
checked bags at the check-in counter (outside security) less than 45 minutes before departure. At some smaller airports they will take them later. At the really large airports they may want the checked bags even earlier.
However, in terms of when you actually need to be at the gate----15 minutes before departure is fine. So long as they aren't completely done with boarding when you arrive you're good.
how is one supposed to get any rest no knowing if there will be enough time to catch the connect to Czech airlines once I land there.
You do all your worrying about these things on the ground. Once you're actually on the plane, you have no control over your arrival time, so there's no point in worrying about it. You'll arrive when you arrive.
My own newest airline hassle story: This past weekend I was in Kentucky. I was supposed to fly back from SDF to IAD on Sunday evening on Delta, via Detroit. However, the plane developed some kind of problem with the heading indicator, and they delayed the Detroit flight to the point where I was going to miss the connection to IAD.
It was only a 40 minute layover. If it had been longer, the whole thing might have been less of a problem.
Anyway, I started looking at options. The first Delta guy I talked to couldn't find anything to DC that night, or sufficiently early the next morning. Nothing into DCA or BWI either. Also, Delta (and most airlines) won't cover the cost of a rental car to get you where you need to go for liability reasons....
Eventually I found a Delta rep who had a clue, and managed to get me transferred onto a US Airways flight arriving at DCA at 8am this morning. Then I had some fun actually making it back to IAD to get my car....well.
All things considered, I kind of wish I had just rented a plane and flown myself to Kentucky rather than going commercial.
