I just dont see any profitable market that employs a clapped out chinese govt gifted 737-300 (the highest cycle example on earth!!!) or even a clapped out fokker.
Not sure that this is correct. My understanding is that ON fleet includes the last classic 737's built (ex Air NZ).
Not aware of the E170 being ETOPS approved (but could be wrong on that), and for my money I'd prefer to be on a Boeing operated by a carrier with plenty of experience in remote island operations.
