I personally use A3, and I have had no issues with them. Communication over email has been proffessional, and the greek call center has low wait times and is efficient at booking reward tickets. reward levels are ok.

TK, AC, and OZ have credit cards in some parts of the world, so if you are into that kind of stuff and it is available in your country, you should keep that in mind.
