Personally I would probably pay the extra $200. I despise the 737 and it’s the absolute worst plane in the fleet IMO. Now, $200 is understandably steep, however adding up 2L boarding, less cramped cabin, quieter ride, and lavs a normal sized adult can actually turn around in, I personally would pay the premium though I also understand that some may find that too high a premium.

Theres also the slim chance that the 757 could get swapped for a 75S, though I would certainly not plan for that.
