Depends what your after. Airliner and the other US based one who's name escapes me right now both concentrate on articles about airlines/airports/commercial flying that are generally very good, what they dont have is current news, and do tend to be biased towards the States. Airliner world is UK based and has an excellent news section and the articles tend to be current, and although european biased do imho have a better worldwide coverage. I always buy them all tho!
