I was a VAX/VMS user and looked at PCs as toys for playing silly games. Until I saw a friend using Eaasy Sabre on a PC. The next morning I bought my first one and signed up with Compuserve. 1994. Sheesh.

I loved how you could construct an itinerary and then change it by adding and removing segments anywhere in the middle. Does EF do that? ITA sure doesn't - you can only add/remove the last leg.
