If you want a suggestion, EGSS to LEMH is a route I do on the 738 but Ryanair operate the MAX there occasionally. 2 hour flight and Menorca can sometimes offer a gusty landing.
The MAX has some pretty impressive range! Imagine telling someone from the 1940s that we can get from Florida to Brazil in less than 9 hours on a relatively small plane with only two engines.
In 1940, I think the longest range commercial plane was a Boeing 314 Clipper, which was a huge, four engine flying boat. It could go 3,500 miles nonstop, meaning it couldn’t even do Orlando to Brasília which isn’t even half the length of our longest flights now. Truly remarkable.
