I have been on the wynnwith 767 contract with globespan for a few months, and from my experience, Globespan invest alot of time and money on their pilots training. I have not had any problems with payments or schedules. To me it seems a very nice contract.
As for the problems which passengers have, that is another topic on which i will not comment on. I am only talking as a pilot and thus, from a pilots point of view.
Any questions, you can PM me.
