In general, we didn't see the 737 as a major competitor. The Fokker 70/100 (328 built in total) was seen as a far greater and closer competitor, which made the Air UK operation interesting
We worked in regions. I speak Spanish and Portuguese, so my main territory was from Mexico southwards, but sometimes other countries, too, for example, getting certification for LCY.. Lots of stories, the good, the bad and the ugly, in my book 'Wings for Sale'
