Right now I travel about 5 times a year domestic and normally once internationally. I have been flying on whichever airline had the cheapest fare on the day and time I was traveling. I did have about 30,000 or so on Delta but gave the points to a charity when they were about to expire a few years back and just never joined another frequent flyer program for some reason.
Yes, I find it much more pleasant in First. Having flown pretty much nothing but coach for the last 10 years I had forgotten how much more enjoyable it was to fly in the front of the plane. Flying coach is much more stressful, squashed in, harried FA's, fighting for a place for my luggage etc etc
What I was hoping for? If I could put in several months or however long it took to get top Elite Status on an airline that I could then continue to fly on bargain fares but be upgraded? I know I would have to keep up a lot of flying (which I actually do enjoy) to continue to have status but flying 100,000 miles but upgraded in a better cabin would be great!
