The on-board crew were professional and friendly and made the trip feel like we were taken care of well. The gate for the flight departure changed three times...not great but not terrible. Considering it was the day of the New Jalisco Cartel mayhem, we can't really complain.

The on-board crew were professional and friendly and made the trip feel like we were taken care of well. The gate for the flight departure changed three times...not great but not terrible. Considering it was the day of the New Jalisco Cartel mayhem, we can't really complain.

I was supose to have a carrey on incluided for each passenger and they made me paid 75$ each at the gate.

Great flight great seats will absolutely fly with you again

Very smooth flights Toronto to Rome and return. Crews were great, food was fine but very narrow seats and limited leg room. Aisle seats on our return helped with a bit more space.

Flying to a far away destination is a miracle in itself, so please take these with a grain of salt. The seats are a bit tired, and need a freshen up. The entertainment could be a bit newer, especially with all services available now. The food really is where we need help. But again, flying is a privilege, so all is good.

The flight and crew were good. Departure and arrival were timely. Check-in was professional and helpful in Malaga on return trip (same on outbound trip from Toronto). The ad before ach program was punishing - specifically for the internet/data service with the content creator that was showed twice in each ad pod. It was so annoying I made an effort to forget the name and would not use the service. Provide an opportunity to fast forward or skip the darn ads once they have been initially viewed.

Flight delayed any hour and couple of big gate changes

The ticket price was reasonable, food was okay, not the best. I would use the service again.

Old plane, hard seats, 1.30 hours delay, while seating on the plane waiting for departure.

I really liked the club service, the temperature was ideal, the flight attendants were so warm and friendly and accommodating the bathroom was easy. Great flight.

On time departure and arrival at LAX - good inflight entertainment - all basic seats on every airline right now begin to feel small after 10 hours!!

I was pleasantly surprised. I've never flown this airline and the seats were comfy, I couldn't select my seat but luckily got aisle and was able to comfortably sleep the whole trip except when they came around with an in flight free meal, drinks then snack at the end. I'd fly with Aer Lingus again. The only annoying thing is you had to pay for WiFi for different hours of usage but luckily I didn't need it

The embarkation at Dublin was a kin to a Ryanair approach, in other words a circuitous and cheep access

Most narrow seat of my life. Easyjet has larger seats. And as I just wrote in the last comment section - Seat 1A promises luxury after a great businessflight. Instead, it's narrow, the seatbelt is 20cm shorter than the one in 1B, it's just a joke.

No snacks, drinks or coffee. No entertainment, not comfortable seats

This was a great flight. I love the way they had general boarding board from the back first by seat row and in general the flight was very comfortable. The seats were actually comfy, and the food served was surprisingly good.

A seat was broken There was a delay of 45min A checked bag was missing in Boston

The service was some of the worst I have experienced on an international flight. The service was rude, the quality of the food was very low. The speed of service was insanely quick. You couldn’t finish your pretzels before the meal came before the coffee came before trash collection came. Then they never came back for 5 hours. They rushed everything so they could get it over with.

A special shout-out to one of the check-in staff at DUB yesterday noon. We had to use the "Closing Flights" counter and we met, hands down, the most efficient person - able to resolve several issues in the matter of minutes, while remaining polite and calming everyone down. Great job, Aer Lingus!

Air Lingus was in no hurry to get us on the plane as sat at the gate a long time before they boarded us. Then they leave us on the tarmac for an hour. They were no help to let me know what I needed to do to get home. I had to navigate London Heathrow with 0 help from them.

The pricing was split into an ultra basic fare with a comfort seat upgrade. This is misleading. Never were we shown an ultra basic fare. What this did because the fare category was ultra basic we could not bid on an upgrade first class seat. All e mails from WestJet were for ultra basic category with my wife and I upset as we could not confirm this with anyone from your firm.The check in counter were not going to allow our carry on but after some checking saw we had ultra basic and a comfort seat upgrade. They could not figure out how this was done. Now we have to go through this again at the gate in Mexico. Unless I missed it - please let customers know the billing in future. Respectfully. Gary & Nancy Moughtin

As someone who never flies WestJet unless there is no other viable option I have to give this crew credit where credit is due. Extremely well done everyone.

Great seats, super comfortable, but no in flight entertainment which was a let down

Single flights to Cancun purchased through third-party, initially had issues printing luggage labels with the lady at the airport Pearson… Was super friendly and assisted quickly despite being very busy

Require more comfortable seats. More frequent water/beverage service. I would like better food choices. Overall, very mediocre. I now only fly WestJet when there are no other schedule options - no longer my first choice.

we were upgraded to business class, not sure why, so the flight exceeded our expectations. Perhaps this was because the flight Cancun to Calgary was a nightmare , not even guaranteed a seat upon checkin at the airport.

Not the fault of WestJet but we had to wait in the plane on the tarmac in Cancun for 1 hour.

The 787 was amazing. Listening to screaming and crying children for four hours was horrible. Small children should be in one section. Seats were very comfortable and leg room was fantastic. Information was very generic on timing.

A lot of people needing bathroom before arrival some didn’t get to use; plane a little small felt cramped but worked still a bigger plane would be nice. Crew was friendly and flight was on time and smooth. No food for vegans 🤔

lucky i am considered slender. but i am 5'7", so in case of emergency it would have been completely impossible to put my head on my lap. THERE SIMPLY WAS NO ROOM TO BEND OVER, ALTHOUGH I AM MORE THAN CAPABLE(AS A LIFETIME OF YOGA WILL ATTEST TO). CRAZY DANGEROUS HOW SQUEEZED INTO THE SEATS WE WERE. i have travelled to mexico for almost 20 years, mostly on westjet, but they have obviously squeezed more seats into the 737 to ,,,,,you guessed it make more money!!!!!! also i had to repeatedly move my 'seatmate' as she kept falling asleep, and as she was definately not slender, she squished me into the window seat all through the flight., if i could have jumped out of the plane and swam to mexico i would have done it in a heartbeat. TERRIBLE FLIGHT, NO FOOD, OH, SORRY, FREE PRETZELS OR COOKIES. LOTS OF BOOZE FOR SALE THOUGH!!!! WORST FLIGHT OF MY LIFE!!!!!

Broke my luggage and I can't get a resolution yet.

There were no TV screens - even in Business class. 5 delays, and only given $12 meal voucher! Terrible!

Flight was delayed again and again ultimately almost three hours getting us to our location at close to midnight by the time we got in and out of airport to destination. I had taken time off work to enjoy an evening at destination and that was now wasted

No food/snack served during the flight. Crew wasn’t interested at all. Flew American First but flying low cost with Ryanair is even better

The flight was good. The only reason I did not say “excellent” was the delay

They could have done a better job announcing the boarding groups and asked for more drinks (water) if needed.

Ac was broken so we deplaned, waited 2 hours, taxiing for takeoff they said the plane would not fly so we went back to the gate and got a new plane which took another hour. In all a 4 hour delay for an 80 min flight.

We were delayed bc ground crew gave the flight crew the wrong paperwork. We taxiied to the runway then back to the gate to get the correct paperwork that no one bothered reviewing the first time we pushed back. Boarding was rude and stressful like it always is. Gate agents and flight attendants are all over 55 years of age, embittered by years of underpayment From AA leading to their passive agressive bitchiness for no reason.

Boarding time was easy & quick. Crew was excellent. In-flight entertainment was great/easy. Seats are too small and not enough room between rows: felt like a sardine/very cramped.

Ground crew forced me to double pay for infant international charges, when I complained about this and told them, with proof, I already paid they threaten to not allow me on the plane because I was “being rude”. Horrible ground management, horrible airline.

We loved our flight attendant (Emma, from Scotland), the meals were perfectly spaced out, and the in-flight entertainment was super generous and delightful.

Why don't they board from the back of the plane to the front. We have to move by all the people and their luggage to get to the seats.

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

With three empty seats across the aisle from me I politely asked the crew if I could sit in one of those seats. They initially told me I couldn't do it for my safety. When I pressed them again they blamed the captain. So which was it? I didn't appreciate either nonsense explanation simply because they didn't want to honor my request.

I couldn't get a vegan meal because I booked via kayak but everything else was lovely

Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer

BAD!!! due to delay I missed my connection in MEX, had to pay for hotel and new flight for next morning increasing my spent for $1,000 usd

Aircraft delayed for two hours due to a technical issue with the rear emergency exit door slide not working.

Superb staff, ingenious seating in Club class. Superb food and service. Loading and unloading. Ample cabin overhead luggage space. But the earphone socket was damaged and did not give binaural audio. Very hard to follow a film over the engine noise. Nor could I get to play Sudoku for want of instructions.

The plane seemd untidy and old. Ran out of food and drinks
