Long time lurker and first time poster. I'm a bit surprised of all the trash talking of the Delta 739ER. While I understand in terms of performance it's a P.O.S. in general, I think DL has done the best they can with them for the most part. They all have mood lighting, giant overhead bins, and AVOD and that's enough for me to deal with it. Have any of you been on United's 739ERs? They are pretty worn down compared to Delta's for the most part and if they don't have DirecTV installed (now free but still dated) there are no video screens installed at all.
Deplaning on them also takes forever, but as does the new high density configuration of Delta's 757 as well. One time I clocked boarding in coach from the gate area to my seat and it was close to 20 minutes on LAX-ATL on the new 757 configuration. The jetways just get slammed with people trying to board especially with the new giant overhead bins.
Anyway, back to topic I don't think it's likely DL would want the MAX considering it's reputation and all the outstanding Airbus orders at the moment. But I don't think Delta is necessarily anti Boeing as they have invested heavily in upgrading the 757 and not grounding them at all during COVID-19 like AA and UA basically have.
