Flew a 737 Max 8 from Hartford to Orlando and now on a 737-700 flying back and WOW what a difference. The Max 8 is almost whisper quiet and I think I’ll have tinnitus getting off the 700. It’s really amazing the difference.
We flew a 737-Max from Anchorage to Chicago a couple years ago. That was my first Max ride. What a quiet airplane! So much better than the previous models. The 787 is similarly quiet.
The only airline that offers nonstops between those two cities that operates the Max is Southwest.
We flew a Southwest Max 8 a couple of months before they were grounded and it did seem pretty quiet.
Bear in mind that it was a new aircraft then and the youngest Southwest 737-700 has seen eight years in service.
