Fuel costs are bigger consideration in long haul flights (planes fly 12 hours a day ) than short ones (planes fly only 4-5 hrs a day). Long flights traditionally were serviced by wide body aircraft , in recent years with longer range and favourable ETOPS regulations narrow aircraft like 737 max and 320neo were desirable for low volume long haul routes. Also at the time of design in 2010 jet fuel prices were at all time highs , fuel prices are at all time low now . Given the surplus in the market , Low fuel prices, drop in demand the ROI for investing in 737 max may not simply exist anymore.

Most airliners, regardless of route length, will fly about 3000 hours per year. 737s might do 4, 5 or 6 legs per day. Fuel efficiency is an even larger concern for those planes because while a long haul aircraft will spend most of its working life at cruising speed, the short haul aircraft spend a good amount of time at takeoffs, landings, and lower altitudes, which burn more fuel per passenger/km.

  The difference is not as high as I had originally thought and has been narrowing recently, it is still a substantial number. Currently 7.5 hrs/day [3] for small narrow bodies, 10.09 hrs/day [2] for large narrow bodies and 12.48 hrs/day [1] for wide bodies.
