Great thread. Especially for those of us a little longer in the traveling tooth.
YES, I remember Easy SABRE. I used it a lot. Also, I was a very early adopter of Compuserve.
With my TRS Model 3. 1980? 81? That I can't quite remember.
I was on Compuserve every night at 300 and then 1200 baud (wow! 1200 baud! Smokin'!) before going with an IBM machine.

Easy SABRE was awesome. Back then, I typically used American Express for travel. I lived in an area of NY that had an AMEX office near my office. They knew something was wrong when I stopped coming in weekly and booking travel. They asked me, "Are you doing things on your computer?" Funny. Yes, I was "Doing Things" on my computer.

I remember executing my first travel itinerary on SABRE. I also remember, now that someone mentioned it, my COMPUSERVE ID. XXXXX,XXXX. It popped into my head for the first time since the 80's. I think I went from Compuserve to Prodigy around 1990. Don't hold me to the dates. Too long ago.

Thanks for the stroll down travel/computer/good-ole-days lane!
