Did exactly the same thing when i went away a few months back, my trip just after the second accident but not before the grounding i believe. Not sure what the options are if you get stuck on a plane you don't exactly want to be on.
My trip just after the second accident but not before teh grounding.
Airlines like Delta show very clearly what type of plane you're supposed to be on. Of course that could change because of maintenance issues, but it is easy to check at least what is scheduled.
