Santa Barbara is a super small and easy airport. Breezed through rental car return, breezed through Security, ordered a coffee and muffin and to my gate in less than 30 minutes. Maybe because it was a small airport we got the oldest plane. Hardly any overhead space and absolutely zero internet. Its NFL Sunday man! That hurt.

What would be infinitely better if for Kayak to not offer this flight as if it was completely different airlines rather than United and then filtering me through some creepy discount site.

Everything works smoothly once I got to Brussels. Flying with United Airlines from Atlanta to Chicago and Leaving Chicago for Brussels was a nightmare though. Slept at the airport in Chicago because my flight got delayed from Atlanta to Chicago. No accommodation provided because united airlines said I had economy ticket.

In general, flight attendants were not very welcoming. Because of delays in departure and luggage handling, we missed our connecting flight. Offered a later flight on standby but available seats were then taken by 4 or 5 airline crew so slept at airport and got home next day. I am a frequent traveler, and this experience was the worst.

The flight was excellent. The crew was great. The food offerings were very good.

Liked the excellent United crew, the food selection, the comfortable cabin and the excellent movie and tv shows selection. The interface on the screen is also excellent and gives the option to let the crew know to wake you up for meals, or not. I disliked the onboarding experience at the Brussels airport. The process is convoluted and was not explained to any passengers. I also don't understand why thee is an additional security screening when getting off the plane from Africa, when there was none when getting off the plane from the US.

Worst and most inattentive in-flight service I've ever had.

The 787 Dreamliner was probably the smoothest aircraft I have ever flown on. Made for a lovely trip

It was a good flight. The entertainment could be better.
