I need to note that this flight experience was generally fine but the boarding situation was absolutely a mess and there wasn’t any actual priority boarding. I rated the experience poorly because I’m am genuinely so frustrated with the crew on United taking the baggage space in first class. This flight it didn’t happen, but the last few flights (when I ironically don’t get an opportunity to provide feedback) have been spoiled because upon entering the first class cabin as one of the first few seated passengers, the overhead bins are full and ‘crew’’ tags are on the bags of those taking space. I don’t intend to infer some sort of a class or caste system but it’s absolutely ridiculous that the crew takes the overhead storage above and beyond their most loyal and lucrative customers. They should not even have economy space IMO. And I’ve gotten grief when I’ve noted to the crew the ridiculousness of the notion that the crew (who are the last off the plane) should have priority over flyers who pay. I hope you find a way to convey this message to United because it’s happening with increasing frequency and I intend to find a way to expose the specific crew members who are doing this on a flight by flight basis. (And I have a day job)

Seats needs to be wirer and food is very poor

Pretty much the exact same comments for this flight, there was crazy weather!

I have been flying united for a long time but now I’m done

1) United economy seats barely recline. 2) I have yet to get United WiFi to work, after numerous flights.

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.
