Which brings up a question I've been wondering about. Why are people holding out for the 330 over the 350? They're both comfortable, well paying aircraft. Both have a tremendous number of orders on the way. Historically the 350 has been senior to the 330, but that's swapped after the last couple AEs. The 330 has more bases, and at the moment, more destinations. Is that enough to justify the change of bidding behavior? Or is there something else going on?
