Sweet! I always fly Turkish Air through Istanbul; wonderful and efficient airport.
But after posting that a few times and reading the responses, I thought I would benefit from the collective wisdom (there are shorter flights, KLM has equal or better service, some political references, airport is too big, the drive to the TA departure airport, statistically TA has as many canceled flights as anyone else- although in the 30 or so flights I've been on not one was canceled or significantly late in arrival,, etc).
So I booked KLM through AMS this time and the next day the posts about AMS started popping up.
And I knew better, I had trouble with lines in AMS years ago, this isn't new.
Booking soon for a trip in October; back to Turkish Air.
