Loved the outlet so I could charge my phone!!!!

I really appreciate that you didn’t force passengers to start checking carry ons halfway into the boarding process. I usually fly American and am almost always made to check my carry on at the gate, only to find that there’s plenty of overhead still available once I board. This was a nice surprise to actually get to carry my carry on on board. Please invest in back of headrest screens for entertainment.
