Would like another option besides water. But not a big issue!

First time I’ve flown United in years. Delta has been our favored airline for years but think United was better today with its service.

Some signs in the terminal for lyft were confusing

The leg and seat room for anyone over 5 foot 9 is really tough. Otherwise, friendly service and good systems form facilitating boarding.

Airline did offer available economy plus seats to on boarded passengers for an upgrade fee. Would have been nice to allow passengers to spread out without fee since the seat was empty anyways and it would help distribute the weight on plane

There is a charge for everything, the seats are tinier than ever, and the ticket prices are not cheaper...

The Wifi service was awful but hey, it’s an airplane. I should have expected as much. Everything else was great.

Extra leg room would be nice !! Glad it was a short flight to Boston and not across country to LA or Seattle.
