Make sure you get your seats booked at time of booking or at the least when you check in and make sure you check in at the earliest to have preferred seating.
MikeFlew with American AirlinesORD-LAXSep 2024
Arrive early, grab a bottle of soda before getting on the plane and open it in the terminal. If you wait until flying the pressure will decarbonize the drink.
Verified travelerFlew with IberiaORD-SFOOct 2024
Use Alaska Airlines. Great attention to detail. The staff is connected with the passengers and they anticipate what we will need , especially when traveling with wheelchair passengers
Verified travelerFlew with Alaska AirlinesORD-PDXSep 2024
Not many amenities at the terminal. I would suggest grabbing anything that catches your eye before you get all the way down. There weren't a lot of Alaska flights out of Chicago, and we were at the extreme end of the terminal.
Verified travelerFlew with British AirwaysORD-CIDSep 2024
Easy hop but we sure went to the most remote o’hare gate I think, prepare to walk a mile!
mauriceFlew with IberiaORD-JFKSep 2024
You should arrive early, take a lighht snack and be prepared for delays.
HeatherFlew with LufthansaORD-MKEAug 2024
Make sure there's enough time between connections to go through customs and recheck your luggage. They will not let you proceed so you can't even try to run and catch the flight if you want to.
IngridFlew with Alaska AirlinesORD-BOSAug 2024
Take a direct flight from Seattle to Boston and do not have a stop over in Chicago
MarcFlew with American AirlinesORD-LEXJul 2024
American can be counted on providing consistent performance flying between Chicago and Lexington.
KashFlew with American AirlinesORD-DFWJun 2024
None. You can’t deal with airlines like AA anymore. Just be glad if they get you from point A to B in time. More than you can ask for these days, with the sad state of affairs with US- based airlines these days
Verified travelerFlew with Alaska AirlinesORD-SEAJun 2024
It was my first time flying with Alaska and I was delayed 3.5 hours. Might reconsider using Alaska in the future.
JonathanFlew with British AirwaysORD-PHLAug 2024
Delta is good, I would avoid American and British Airways
PaulFlew with Alaska AirlinesORD-SEAApr 2024
The flight is long, at over four hours. I would try to get a window or aisle seat to be more comfortable. I would check with other airlines that allow you to choose your seat even if you are in the economy section. I would bring your own food on the plane as the service was sometimes sketchy.
EllenFlew with United AirlinesORD-DSMMay 2024
The flight is short enough that full beverage and snack service is limited or not offered at all. On this flight, we were offered orange juice or water. It makes sense that they can't do the full service, and doesn't bother me, but it's something to be aware of.
AlexanderFlew with Spirit AirlinesORD-LGAMay 2024
Know your connection options — specially when LaGuardia Airport (LGA) only has buses going to/from the airport to the rest of the city. Luckily, the one to the subway station (Q70) is free-of-charge to ride on!

Use the find my gate feature on the flights phone app if available as the airport is a bit confusing

If you miss your flight ask any alaska agent to how and where to rebook the flight.

Fly out of Midway airport instead of O'Hare because its smaller and easier to manage.
Verified travelerFlew with Spirit AirlinesORD-ATLApr 2024
Some areas of the airport were cold, others were warm. We had to seat in the warm area which was far from our gate. Not sure why A/C is not properly adjusted at O'Hare Airport
UzomaFlew with American AirlinesORD-DCAJan 2024
ORD and DCA are nice airports with plenty of space. ORD is always busy so allow ample time to drive there, drop your bag, and go through security if you don't have TSA pre check.

Be prepared to walk long distances in Charlotte. Make sure your layover time is sufficient to transition between arrival and departure gates.

United or American are the best airlines to fly to DC
SeanFlew with Alaska AirlinesORD-SEAJan 2024
Signage for hotel shuttles at O’Hare is poor. Restrooms were surprisingly clean. In winter especially, there are going to be delays.
GerryFlew with United AirlinesORD-LAXJan 2024
The one unfortunate item with this flight, because the flight was full, everyone in group 3 and more had to tag their carry on luggage and have it checked. I my opinion, there was lots of available space on the plane for pack packs, coats etc that could all have been put under the seat. We cannot give up our carry on because of the medical needs

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

Flight did not have seat back entertainment and the wifi was iffy.

Pretty standard flight. Delta has a good selection of movies.

The WiFi has been awful on my last few Delta Air Lines flights.

The seats are uncomfortable, feels like a small seat pad on plywood.

The seats are uncomfortable and there was no power to recharge a phone.

Flight heavily delayed. No food available despite purchasing an upgrade. No in cabin service.

They need to improve their boarding process. Group 1 and/or paying first class passengers shouldn't be in the middle of boarding process

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

I still prefer Delta, but Delta doesn’t fly to State College PA.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

The flight was bumpy. No Breakfast or coffee was served, not even a bottle of water. The food was okay but odd. Rice with peas instead of couscous with some unknown green thing. United Airlines did not tell me that there was VERY LIMITED HANDICAP SERVICE IN NAPLES. De-plane via 20 aluminum steps. Taken to Van. You must walk into the terminal, find luggage, and then walk out to the rental car pickup spot that is 1 block from the terminal.

Crew did their best but the plane configuration is too tight if you're bigger than an average sardine. Controls for the entertainment system didn't all work. The aircraft hadn't been cleaned in awhile.

Didn't make it dir to delays - no support from United staff

My flight was delayed for a whole day, so I lost a day of my vacation.

flight delayed, was put on another flight after standby queue, luggage was misplaced and arrived to me 3 days later

The baggage handlers broke the handle on my bag that they put under the plane that I checked on the jetway. They traded it out for a less quality bag in Tulsa. But, they said they would try to fix it. Bologna! There was no fixing that bag handle. Someone didn’t care how they treated the bag.

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

The flight crew was fantastic! Which the seats had a small TV.

The flight was delayed till next day ! They kept delaying every 30 minutes then after 3 hours they delayed it till next day. We kept waiting in line standing more than an hour to get the hotel and meal vouchers. There was no communication at all. Everything was bad

Smoothe flight. Pilot and crew did a great job. Uncomfortable seat in this jet, felt worn out

seats were way too small. Too short of a flight to offer amenities.

The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

American is a steady for me. I always get what I expect from them. Sincere effort to get me from one place to another.

BAD. As a family could not sit together. The gate agent told us there was only one seat in the middle left, when we got on the plane the situation was very different with whole rows of seats empty

Atlanta airport gate area floor and nearly all seats disgusting. Spirit airlines crew fantastic!!

Over 2 hour delay due to “weather” but all other flights were taking off with no issues. We felt lied to the entire time as well.

Everything was excellent and as expected. The boarding process was great but deboarding was a bit slow. No fault of the crew; it just seemed like the passengers didn’t want to leave! 😂

waited 5 hours to tell us it was cancelled even when they knew

Easy! As long as you don’t mind no frills, our flight was enjoyable and on time

No carry on available to purchase at any point, charged for water, no power to charge phone. Other discount airlines have this.

Okay for the most part but Good boarding and on time

The flight was delayed and the announcements were hard to hear, but the crew was great

Smooth enough, delay-free and safe. All went as expected,

Not acceptable having both flights delayed and not real reason for .. plus paid for luggage and getting my bag ripped out .. very disappointed.

Stop changing gates at sfo. When you are elderly going back for it’s not fun.

We understand and comply with Frontier’s bag sizes. We’ve had some problems in past while having to await other passengers who do not understand the baggage restrictions or have not prepaid and that is usually our biggest concern (others delaying us) with flying Frontier. Flying OUT of ONT, however, has always been a great experience. I’ve also noted even on delayed Frontier flights very knowledgeable pilots who manage expectations well.

There was no easy way to check in. I don't want to install an app to checkin. I will use alaska from now on because they have a web check in method that is easy.

The crew was ghetto lol I felt like I was on an inner city field trip

Horrible! The short distance flight ended up taking 5 hrs! There was a 3 hr delay for the flight to take off and there was a 70 min wait on the tarmac for some bogus reason that the pilot said the gate he was supposed to board was taken up. After a 30 min wait he said the plane that was supposed to push out of the gate called a medical emergency and 40 min later he ended up boarding another gate. For the initial 3 hr delay there was no information/alert about the gate or delay in the app or the boards up until the boarding time and even beyond! Had to walk all the way to the end of the terminal to find the frontier staff to ask what was going on. Avoid this airline at all costs! If you have carryon bags or checked bags , their prices come equivalent to the prices of more reliable airlines. They are the worst in timeliness at 60% (reported as delayed) this year (check the data) by a high margin even compared to the second worst airline. If you are ok with having a miserable flight experience with the odds close to flip of a coin, feel free to try them. If you value your time , money and flying experience, stay away.

There was nothing to like, flight delayed had to move to different departure areas, disorganized to say the leasr

Delayed for two hours due to trivial issues. No reimbursment. Also on arrival further delay due to terminal malfunction.

Our flight was canceled for no known reason. We weren’t told until we were checking in at 5:00 am. This was after our last flight with Frontier where we sat on the plane for three hours (not an exaggeration) before we took off because of a mechanical issue. We won’t be flying Frontier again.

Allowed me to chose my seat without extra charge (I purchased full-price ticket) and boarding was in group1. Didn't even serve water.

I went to the Frontier counter in San Jose at 1030am or so on Sunday 10/13/24 to see if I could get an earlier flight to San Diego in lieu of my reserved 630pm flight. One thing led to another, and I was able to obtain an open seat for about $ 56. on the earlier flight. Fine. Then the agent asked if I "was checking a bag". Not knowing that carry-ons cost extra per Frontier policy, I thought that she meant a regular checked bag. Therefore, I said no. Once I got to the gate, the same gate agent who sold me a ticket told me that I had to pay $99 for a carry-on, and that all bags were extra on Frontier. Having never flown on Frontier, I was not aware of this. Part of the issue was that she was not a native English speaker, so there was a miscommunication as to what "bag" meant. I would have preferred for her to have clearly let me know at the front counter that any bag including a carry-on cost $99. It would have had the same outcome, as I had to take my carry-on. But it got hectic at the last minute at the gate itself. The baggage policy should have mentioned "including carry-ons" when we first spoke.
