My thinking is starting to be we will only see the 737 Max return as a cargo plane. WN will sell them to cargo companies. Long term affect on WN will be devastating as the company sticks with the new business model of lots more higher fair seats to make up for loss of overall seats. Game changer as it will drive loyal customer to other airlines.
I recently flew on what must have been a leased old 737 to WN, it was not a nice site inside.
2019 I had the far worst travel year on WN in over 20+ years and walked twice with WN boarding cards on phone to other airlines and purchased walk up fare tickets.
The long term one airline model business plan worked great, those days are now gone. Time for a new business model.
