I used Martinair a lot on their AMS
flight. That was when KLM did not service MIA
yet. The flight arrived in the early afternoon and my connecting AA
flight to LPB left always in the late evening, which left me six hours to spend in Miami. Not bad.
I have good memories of Martinair. If you are a typical "business traveler" you will probably not like Martinair. Their flights are always full, seat pitch is cramped (they get 512 seats in a 747-200) but the atmosphere on board is always loose and fun (a bit like Virgin Atlantic if you know what I mean). Lots of people flying to their vacation destinations and attractive flight attendants doing a good job and speaking an amazing number of languages. They are also very nice to kids, giving them special attention and offering them toys and special meals. Not many delays (at least I did not experience many) and cheap, very cheap.
I you fly Martinair intercontinental you will most probably end up in a 767 or a MD
-11. The first couple of rows on their intercontinental flights are called "Star Class". This is their business class. It is not bad but not comparable to the more well known carriers business classes.
