Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.

Quick and seamless boarding. No entertainment but fast Starlink wifi for this short trip and the staff was really friendly.

We boarded late. The crew at the airport was dismissive. The seat cushion on the plane was uncomfortable.

Very thoughtful flight attendant offered me water immediately since I had run to make my connection.

Door to door, the crew and staff were amazing. It was a stressful travel day with delays, but they were focused on customers and doing what they could to get us to our destinations.

I dread trans-Pacific flights. They are very long. This was my first time on Universal, and it was my best crossing ever. The staff were professional, the hospitality was great, and the food was delicious. The entertainment system filled the long flight hours. I will seek out Universal flights from now onwards. 🙂

United has come a long way, it’s been a fantastic experience traveling with them.

Even though we were delayed, we were able to make our connection

Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

Great crew, excellent landing, good food. Over all great experience. Thank you!
