Even with a stop, it is only between 3 1/2 -5 hours flight time between Buffalo (not sure though if that is where you would fly out from though) and Richmond. By the time you try to transfer to a train, or bus (and the stress of all that), it may not be that better a deal. Agree it is a good idea to look into taking the train all the way (maybe about 7 hours?). I would be inclined to stick with one type of transportation to Richmond-either fly all the away , or take Amtrak all the way. Greyhound could possibly be an option as well but would probably be the least pleasant option.
