allow plenty of time for security check. Take all liquids, cream, make- up, foundation etc. out of your carryon luggage. a lot of travelers had their luggage pulled over for open bag check. This slowed down the screaming process considerably and caused me to lose my flight.

Not constantly changing the price DURING a booking. Felt like bait and switch.

All very smooth airside. Check-in counters were understaffed. The wait is too long. Only two, then three counters were open. Waiting time of 35 minutes is too long. Pls review your rota.

Very fast boarding. Crew members were super nice. I loved it!

My luggage got lost and until today there is no solution to the problem. It's still missing

Only food for sale. Did not even offer water. No entertainment

Checking was efficient and quick. Adequate luggage space. Food for purchase only at high prices

Terrible. For clarity - this was the Level flight to Boston. Not Vueling. Would urge customers to avoid this airline. Gate agent was singularly unhelpful. He was argumentative, rude and went out of his way to ensure that every penny was collected for the baggage (which we realized given how early we were for flight we could have saved hundreds of dollars if we checked in on app). No onboard entertainment or WiFi. Half of the front section was empty because the seats did not work! Plane was falling apart.

The flight was delayed and nobody was able to inform me about the new scheduled time and gate

The whole flight was coughing and farting all the way. It was impossible to breathe. If people are traveling sick they should either not be allowed to fly or made wear masks

Bought check in baggage but couldn’t do it at the kiosk, had to line up just to get baggage tag which was a very long queue with only 1 customer service agent handling all vueling flights. Had to wait about 45mins just to get a bag tag and drop baggage.

Service and food was amazing. Aircraft configuration is weird - stare at a stranger at take off and landing, during flight someone is crawling over your seat. It was lame.

The flight attendant does not pay attention to my "call" button more than 3 times when I need a drink.

I loved the food choices and the attentiveness of the crew but boarding was chaotic.

I don’t think you’ll like the shoulder require people to pay to reserve seats. Also for the people in the bulkhead row the luggage locker nearest to their seats should be vacant. Both sides were filled with crew or airport items.

Awful. Flight was late. Follow flights cancelled. No person at the British airways counter for hotel voucher. Awful service.

I thought we were screwed having to pay an additional $300 to pick our seats. My wife and I think it’s important to sit together on long flights and British Airlines use’s that against us charging over $300 on top of an already high fares. In the future, I’ll try to avoid using British Airlines, and KAYAK and stick to American or United.

Yet again BA flight was delayed. Only one delayed. No updates from ground staff. Plane was dirty and staff were disinterested.

my flight was canceled and rescheduled for two days later

One if not the best Airline I have traveled so far. My only complaint is that flights where delayed.

Free food and drink! Got a late start due to mechanical problems w a luggage loader.
