I took a long time to start boarding past the announced boarding time. It was the replacement flight for the flight we were supposed to take the previous day. That one was cancelled because not enough airplanes were planned to be in operation. I don't like that you have to pay extra for food and luggage.

I took a long time to start boarding past the announced boarding time. It was the replacement flight for the flight we were supposed to take the previous day. That one was cancelled because not enough airplanes were planned to be in operation. I don't like that you have to pay extra for food and luggage.

This leg of the trip was ok, though the check in agent could have given us assigned seats. I have a feeling though that agent could not as it became clear later on. Please see below. However, the leg from Zurich to San Francisco was horrendous. We only had less than 1.5 hours to transfer to a different gate using transfer train. We asked at the business lounge and were told to see the gate agent. When we went there there was a long line. As we approached business class desk, we were yelled at and the agent said "I will not talk to you". After a long wait, we were then told our seats will be assigned at the boarding time!!! After a time, the agent announced for volunteers as the business class was overbooked. We did get seats in the end but were separated at which point, we just decided it was not worth trying to ask for seats. I am not sure I will ever use Arrant Grant. I understand the Arrant Grant need to charge commission. However, what Lufthansa charged $10315.80 Canadian dollars ($7316.17 US dollars) was so much less than $12670.80 Arrant Grant charged me. I think commission of $5354,53 US dollars is too excessive. Also, I tried to upgrade to First Class and was told that we had upgraded once already and couldn't upgrade again. So, a terrible experience.

As a European regional carrier partner of Swiss Air/Luftansa, Helvetic did a great job.

Food too spicy. Very late boarding. Premium Econ seat did not recline.

picking up the meal trays quicker afterwards would have been nice. In tight spaces needing the drop down tray open with plates and wrappers on it feels very cluttered and uncomfortable. I loved that wheat bread. Im vegan and not sure what was vegan.

Checking in and crew were great. Seats in front of you in economy recline so much that you can't get out of your seat. I guess thats why its economy....

I liked the flight experience. I don't like the leg room.

There was no entertainment on the plane no screen to watch anything from Zurich to LAX boarding was slow and very unorganized. as a result there was delayed I bouught in flight internet and it did not even worked after 10 minutes. no crew helped . I would like to get a refund on that. crew was not friendly

Flight was on time. Could have been a little more comfortable. Baby cried all night.

Easy check in The flight was a bit delayed but the crew and flight were excellent

Luggage delayed and delivers 24 hours later … broken. No resolution… no response. We don’t have a suitcase for the rest of our 2 week trip

Terrible flight. 1. They’ve only one option for food. 2. Seats are very cramped and screens are tiny 3. No pillow or blanket provided on long haul flight

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

That was a short flight by the only time I could actually sleep

How can a national carrier and part of Lufthansa group not even provide complimentary water and a snack in such a long flight ?

Terrible seats. Whoever designed the seats should try taking a long flight in it themselves.

Food quality is deteriorating each time, last year was very good. I avoid the plane food lately.

Been flying on various airlines, all over the world, for 50+ years. The food on Brussels Air was easily the worst I ever endured.

my husband's monitor did not work. there was a visibly ill family in my husband's row.

The check in process and dropped bags was easy and the agent was so kind. I usually dreas that process and it can be uncomfortable and frustrating/difficult at times. I had a great experience

Sitting on the last row in between the aisle and a massive person, all people going to the bathroom bumped into me including the flight attendants.

The terminals are far away, be prepared to walk. Also, You climb stairs to the plane since there are no aero bridges. Boarding was haphazard not in multiple groups, so stand in line early. Hard to find place to stow cabin baggage if you are behind in the line. You can purchase food on the plane. There are vegetarian options.

sadly in Basel & Naples- no jetway we had to climb up and down stairs with our max size carry-on luggage, which was not fun!!!

Long delay resulted in my being unable to catch a train home and resulted in an additional £76 cost for an Uber

The on board air steward really made the journey. He was very entertaining

Worst airline in the world, will never travel in it again.

I am writing to share how your teams can better serve your youngest customers. On 9 January, 2024, I boarded and then de-boarded a flight with my 6 month old daughter. I have four children and travel extensively. Delays happen, but the stress my daughter had to ensure was avoidable with simple and straightforward actions. (1) communicate delays to customers -- Breastfeeding mothers are constantly timing feedings. If delays were communicated, I could have camly fed her instead of attentively waiting for priority boarding. There were no announcements and no updates to the monitor; (2) honor the priority boarding process -- While a staff member waved us in for priority boarding, half the plane boarded while the "priority check-in" representative was preoccupied; (3) anticipate challenges creating unnecessary stress to infants -- after completely ignoring the priority boarding procedure, and knowing that the plane had not even arrived, the team could have offered to board us last. My daughter could have been calm in the waiting area while breastfeeding. Instead my 6 month old was completely unnecessarily stressed in the middle of the jet bridge, packed in solid.

Staff had been really impolite at the boarding area and for both ways charged high extra fees without a reason. For the check-in luggage which was measured 3.5 kg and was confirmed by the stuff to cost 40 € , 60 Euros had been purchased from our credit card. When confronted staff did call us both liars and claimed to never have announced anything. Flight back , when not wanting to press a backpack in a measuring metal instead of hand measuring , staff got angry that one did not follow her order, which was than escalated by the team. Although carrying a baby anyways staff did not offer any help in the unreasonable process and than charged again extra money. Cabine crew has been friendly but this experience LL lead to not booking easy jet at all in the future. Check in process in Edinburgh anyways chaotic,to the family check-in and disabled check-in everybody else was guided for check in process, so people just getting in between each other, not possible to monitor your own stuff.

Cancelled last minute, I had to travel 13 hours by train at night
