Riding a Brompton with a power meter.
My times on B757s were on busy short haul routes where a B737/a320 wasnt quite big enough which influenced my puzzling of why a 'big' B737 no longer exists and I vaguely remember the airlines route map included some longer routes presumably served by the same plane. My first time in B767 was also a busy short haul route, and another an less busy atlantic route.
The "big" 737 does exist - the 737 MAX10. That seats 230 pax which is about the same as a 757-200.
Boeing only ever sold about 50 757-300 out of over 1,000 built so they realised the market for a 250+ seat narrow body basically doesn't exist. Hence the 787-8 can be configured down to 220.
