I am about to relocate from Phoenix to Malta. MLA will be my new base for what look like many years, if not for good. The company I will work with only flies economy and in the beginning it will not be much flying but since that will add up later I would like to get a jump on a good program.

Let's talk routes.. The following routes will take place once month each;
MLA-LIS
MLA-FAO
MLA-NCE
MLA-CDG
MLA-OSL
MLA-BGO

Other random flights that I am aware of at this point;
MLA-BZE
MLA-SOF
MLA-KBP
MLA-PMI

Also I guess I would be going home once a year or so; MLA-MIA

So there it it, any suggestions to what European program I should focus on? On board service is important so is lounge access for delays..Also when flying alliance metal..

I have traveled very little internationally, how do carriers over there compare to what I am used to on UA and US? Is there someone that sticks out?

Who would be my best bet? Thank you for reading and any info and input you might have.
