I don't think traveling nowadays is less fun; it's just different. (That and you're being nostalgic

.)
I don't miss the looooong check-in lines (no OLCI or kiosks available), the paper tickets, boarding by bus (still available in some places), the high prices. Oh, and remember smoking sections?
Some relics are still around (e.g. movies shown on projectors on raggedy DL 767s) although I can't wait for them to disappear forever.
