Return flight was perfect. All on time and no hiccups. However, going was another story. I don't blame United for the weather, but I am rather disappointed in its response to my getting stranded in my layover city for the night. United gave me a $20 food voucher. That's it. But besides this policy, the employees were incredibly helpful rerouting me to my final destination in Fort Lauderdale, FL. So overall, 8 out of 10. 10 out of 10 for flight comfort, inflight service and before flight service. 5 out of 10 for layover handling.

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.

There were no vegan options for first class. Even though we were promised the satellite internet for free, we received NO wifi at all. Even though we were promised a 20-min early arrival, we ended up over 30 mins late.

Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.

food /beverage service was limited to one time which was unexpected for a flight that long. food wasn't very good.

From the boarding crew to the FAs was such a good team. All with smiles and positive energy. The pilots made an announcement of us waiting on some passengers who were late landing and I didn’t hear one person feel like it was an inconvenience which was wonderful. Massive kudos to all that worked that flight. Everyone was united. 😊💙

Smooth flight, easy boarding process. Made up time in the air with initial delay due to weather pass through

awesome team work seen since on board till off plane in my destination. thanks you so much.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.
