I was modular and was very lucky to get a major airline to pay my TR. But if I was starting out now and I could afford it then I'd go integrated with one if the big 3 FTOs. As much as I don't like it they very much have exclusive deals with the airlines. The self improver route is on it's way out unfortunately. There are a few TP operators out there but it's just a matter of time before they tie themselves up with one of the big 3.
