Daddy ho
Norwegians 738 are routinely do these routes including LPA/TFS to Tromso non stop, I agree the 757 is one of the best all round aircraft ever built but a bit greedy on fuel for much of what it was designed for, the 737 MAX is up to a MTOM OF 82.9t and a range that allows New York to London, which is more than long enough on a 73 !!
