Nice flight but have wished United let me have a carry on bag on board

Mar 5, 2019

I don't like basic economy. Thought I could still have a carry on and personal item. So won't do that again. Also would prefer to select my seat.

I like everything

I would have loved to have been able to sit next to my son. We were both placed in middle seats so no one wanted to switch with us so that we could sit together.

Entirely satisfactory

My only complaint is Expedia’s poor booking experience related to Basic Economy fares. I haven’t traveled in 4-5 years and wasn’t aware that I booked Basic Economy. It was very didsappointing to learn that I couldn’t upgrade to standard economy later on when I realized this mistake.

In flight entertainment did not work despite downloading the United App. Connectivity was terrible. :(
