Top tips for finding cheap flights to Mexico

  • When flying out of Seattle, you will use Seattle-Tacoma International Airport (SEA), which is one of the busiest airports on the west coast. For that reason, you should try and get to the airport at least three hours in advance so that you can have ample time to go through the long security lines.
  • If you’re flying to Mexico to visit Cancun, then you should book a flight that lands at Cancun International Airport (CUN). This is the main airport serving the city and therefore the most ideal place to land so that you won’t have to deal with intercity buses from Guadalajara or Mexico City.
  • For anyone planning to leave their vehicle at SEA Airport, ensure you compare the prices charged by airport parking and the off-site parking lots. In most cases, the off-site parking lots charge lower rates and you could end up saving a huge amount of money.
  • Even though pets are allowed in the airport, you should ensure that you keep them in a safe carrier while at the airport. It is also your responsibility to ensure that they aren’t a nuisance to other travelers.
  • Public transport is not available from CUN Airport to Cancun. Therefore, when flying to Mexico through CUN, you will have to take a taxi or use the airport shuttle to get from the airport to the city center.

Wheelchair assistance was provided in Seattle and was very gratefully accepted. Thank you to the Alaska staff.

I payed for a window seat and was assigned the middle seat. The window seat just so happened to be open. Which made the ride alot more comfortable. I think I should get what I pay for without having to buy extra fight protection. If I pay for it first that should be the end of that seats history because it's now spoken for. That alone might make me think twice about using this again

We were flying 1st class for a special occasion. This was a Hawaiian airlines flight. It was exceptional. Very comfortable seats and space. Extremely attentive crew. Food was great for airline food. They provided tablets to watch and full headphones to listen. This was the best airline experience I have had in decades.

Didn't care for the crowding at the gate area at SEA TAC. Not a fault of the airline.

Loved the staff ease of flying snacks and free movies and WiFi

you could have gotten me there on the day I was supposed to be there, not a day later. Paid for 3 nights at a VRBO and got to spend only 2 nights there.

Flight crew and gate staff were very polite and professional. They were very helpful and made my trip smooth and trouble free

Our flight was delayed BY 6 hours and the reason it was delayed because they needed a part which made me be worried about the plane. They did not have any TVS. Add the seeds and this was a very long flight. But they also only offered snacks, and even after we waited the 6 hours of being delayed with that, we still have to pay for drinks. If we we wanted one

all crew, pilots and attendants were fantastic. Both to and from flight to SEA, attendants went above and beyond.

Late boarding, but the flight was smooth and the crew was accommodating.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

Food was surprisingly good but the WiFi was not great

Easy boarding with an extremely kind attendant. Seats were spacious and we had 3 seats for 2 people so we could stretch out. Comfortable air flow and very attentive and hospital attendants. Bathrooms and food were the only negative. Bathrooms were so small you could hardly get in and close the door. I don’t think an obese person would fit or a person with a movement disability. Food was the trending food for flights, nonexistent. We spent $40 getting sandwich and snack at airport for our 6 hour flught.

Overpriced tickets and attitudes to pay for such service. So bummed.

Flight was delayed long enough that I was misding my connecting flight. The agents could not get me on a comparable flight, nor could they get me s Main Cabin seat I had paid for, nor could they get me on a comparable connecting flight. The gate agent would not issue meal vouchers, even though I was delayed over six hours! I had to spend over an hour and 15 minutes with customer service on the phone to See if they could get me on a better flight and get a meal voucher. Customer service was not helpful enough in trying to find alternate flights and it Ended up taking me 24 hours for a 12 hour trip!! Delta does not provide upgrades NOR will they even give you a pass for a few hours to their lounge. They claim that they do not issue daily passes to their lounge anymore. I call BS since this would be no extra cost to them to provide excellent customer service and give you a few hours to relax in comfort when you’re sitting in a crowded airport and your flight has been screwed up for that many hours.

It was an overnight flight and I desperately needed coffee before we landed, but Delta does only one beverage service, and that is shortly after takeoff, not before landing at 5 am.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

Aeroméxico cancelled my ticket without advice AND It make a last minute mess in my intinerary, no solving my situation, bad advice and bad customer service

The ground staff were not as friendly and nice to the passengers as the air crew. Flight attendants, cockpit crew were great and very nice to everyone on board.

My flight was delayed, then I got transferred to a new flight that was also delayed- which wasn’t Aeromexico’s fault, it was because of weather conditions. Most of the crew was very nice and patient, except for one or two flight attendants who were rude. The entertainment wasn’t on, so all the screens were off.

My wife's entertainment system did not work. Payed for flight upgrade but did not receive advertised "free WiFi".

Annoying that we had to go to departures and get boarding passes. Should allow us to be booked all the way through, this is the only airline i have this problem with in MEX. Late boarding and take off

Lousy No wheelchair. As normal at Atlanta Cheap airline Cheap aero plane. - Neither entertainment nor food on a 5 hour saga

The airplane was an old airplane, seats were very uncomfortable and very little space, they changed my seat and that was no option to get back into my seat even when I was traveling a senior who required assistance.

This is not a low cost airline. Stop acting like o e.

Aeromexico crew made me check my hand luggage in the door of the plane. As soon as I reach Mexico City, I notice that my luggage was opened and 8 games of Nintendo Switch were stolen (700 dllrs value aprox) (the console was there) but the games were stolen. I am very dissapointed of Aeromexico and all the crew. Instead of being a good trip, It was a sad trip

Ok. But we arrived to a remote terminal which meant that a bus had to take us to the terminal building

Any flight to ORD after about 2pm this summer has been challenging. Flight was delayed getting in (coming from ORD) and that led to it not leaving before a ground stop due to lightening before they could fuel the plane, and so forth. They made up some time but we were still late in arriving at ORD, and that led to missed connections.

Food was ok, but not as good as I have had before on AA.

No issues. They did change our gate FOUR times in about 30 minutes which was mildly annoying but the flight was fine.

Great flight. No issues at all. I still think boarding could be more efficient but otherwise, a good experience.

Pretty good. The food was just mediocre, the boarding and crew were good.

The comfort of the seats was great, the crew eased my child’s anxieties and the fact that I had full cans of my beverage choice was great.

My flight got switched and my prepaid bag didnt transfer over properly so I paid to check ANOTHER BAG. I was placed in a middle seat and it was just miserable. At least it was a bulkhead row so I had legroom. The flight just never seem3d to end

4 hours late, including over +1 hour waiting in plane to take off. Baggage left behind too.

Sat on the ground in Cincinnati for 50 minutes before deplaning

While waiting to claim my checked luggage, I discovered the airline had lost it. After a long wait and inquiries, I discovered it was on another flight. Fortunately, the airline finally sent my luggage home.

In Mexico charges too much for my luggage and I ask for help and nothing one lady she just disappeared 😡😡😡😡😡never going to fly there

Confusion over extra fees. Held up on ramp during boarding. Thin seat cushion. Minimal leg room.

The check-in is either at a kiosk that didn’t allow me to check-in because my middle name was not on the reservation or at an agent that cost $15.

Better communication about delayed flight. I am thankful for a small credit for late flight.

Liked on time, rear entry and exit from plane Dislike the use of duct tape to repair seat rests

Terrible. And they charged over $400 just for luggage. And threatened that I would loose my flight if I didn’t pay. So I didn’t have another choice but to pay.

They check you everything before entering to waiting room, if you have any liquid they take it away even if you buy it inside the airport, no recommend volaris, for mi know Alaska airline is better

They don’t give anything for free you have to pay for everything which it’s expected but at least give out water and a snack as a courtesy for flying with them.

The worst. Kayak sent notification at 2am and 10am regarding the delay. Then sends a notification an hour before original depart time that it will depart on time. I had to wait 8 hours at the airport. My family had to pay for lodging in Guadalajara where I was landing for pick up.

The flight was delayed an hour and a half, and they would not update the board on when the flight was supposed to take off. Once the plane arrived, they started the boarding process before the plane was even ready for the passengers so we had to wait another 45 minutes on the tarmac while we waited for the plane to be ready for us. In my opinion, there is no point in starting the boarding process when you are not ready to board the plane. This just causes a crowded gate with everyone from zone one and zone two standing up going nowhere.
