1. Most important for f2f
Have to say availability of international flights and upgrades.
2. HOW many miles do I fly each year.
I would say at least one international flight 10000 to 25000
3. Class if international over 6 hours Premium Economy or better.
4. I travel for pleasure.
5. Flights to Canada and NC are most frequent routes.
6. I usually fly out of FLL or MIA for most international.
7. VA 15,000
Qantas 29,000. ALSO have Am Ex to transfer
8. I love Virgin partly because of upgrades through F2F and comfort- but hard to connectt To the rest of Europe.

I'm still trying to have the hang of using Fprequent flyer programs. I do know that it is much easier during Spring. Not sure what to do with my Qantas points.
Any thoughts?
