Hi everyone,

Thanks for all your responses!

The reason I wanted to go in the winter is because we promised some people that we'd visit them around New Years time. Obviously, if that's not possible we'd just go some other time but we'd like to honor our promise. Plus, the holiday markets that cordelli mentioned sounded really nice

They live near Munich so we thought Munich was best, but we are planning on staying an extra few days to maybe see some other cities like Berlin.

I really just started traveling about 2 years ago. I'm only part of Jetblue's TrueBlue program. I'd really like to join an international frequent flyer program because I do plan on traveling much more often. Is there a frequent flyer program that would be best for someone that flies probably 3-4 times a year (domestic and international)?
