Reviews of the top 5 airlines serving from Phoenix to Illinois
Flight left on time and was early landing. Seats not comfortable and not enough space…
Flight left on time and was early landing. Seats not comfortable and not enough space…
For the first time in a long time, the Wi-Fi actually worked the entire flight! The flight crew was amazing as usual.
Great flight. I didn't get a drink because I was asleep whole on the flight.
It was good from LAX to Phoenix, But the connection in Phoenix to Tulsa was not that great. The staff on both flights were great. The choice of free entertainment was ok nothing to brag about. The 45 min delay because of some electrical issue wasn't great from Phoenix to Tulsa. We sat there with hardly any air, The seat I had was between windows so the side of the plane pushed in on you. My being a bigger man it then made the seating area uncomfortable. The seats on the plane had no power to connect to recharge your phone or anything. I would recommend that they should look into a slot or clamp to hold your phone to enjoy while watching the entertainment choices hands-free. Also make it possible to raise the inner seat by the window be able to raise the arm rest up to make more room for larger people to set more comfortably. I would also say other then that stop price gouging the airfare or nickel and diming everything. Not fair for people having to fly for emergencies and be paying for higher prices due to the season or holidays. Your making your money either way and the cost of flying is still going to be the same regardless if there's 100 people or 200 people.
Mediocre. Boarding is now unpleasant. The employees, once friendly and nice, are now regularly speaking sternly to passengers, badgering them to do things right so they can take off on time and gate check bags because they don't have enough overhead bin space. The pretzel snack was crushed flat and broken into even smaller pieces, which happens frequently lately. Drink service was suspended before they reached my row.
WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled.
All good except once again bags took an hour at Midway Airport Happens all the time. Ridiculous
mandatory demand customer to check their carry on because not enough people check bags.
First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.
Delayed 4 hours due to mechanical issues. No mention of compensation for being over 3 hours late
Even though the incoming flight was delayed by 20 minutes they managed to get us to SFO 15 minutes early.
Gluten free snack options and meals that offer both gluten free and dairy free.
First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?
We purchase first class seats for the first time for multiples of standard economy ticket. There was no access to the club lounge and no priority boarding. The meal and the service once on the plane were superior and the seat was nicer, but not worth the price difference. I will be happy to seat in economy and spend the difference on more travel.
I upgraded my seat and was promised it would be next to the emergency door for extra leg room and they said it was premium plus but it was at the back of the plane...same thing happened from Newark to Dubai
Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.
After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.
The woman gate agent in Phoenix was none too sympathetic about my check-in process as I am relatively new with using apps. I almost did not get on because she said I did not check-in. I thought I had via Kayak where I purchased a very expensive ticket. Lesson learned but to be told I may not get on as a matter of factly was difficult to hear.
We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again
Flight was delayed, which put a great stress on us, about potentially disrupting our two subsequent overseas flights. Had to run through the airport, but we made it. Comfort of the seat was non-existent.
There was more leg room in what was most likely a basic assigned seat (row 25) then on other airlines I've flown lately.
They lost my luggage and have ruined first day of my vacation. Still don’t have it. I have nothing. I also paid for a seat I did not get. They changed both our seats with no notice. Will never fly this airline again.
My overall experience with JetBlue was pretty poor and disappointing. We originally booked a DIRECT flight home from Boston on 9/28 at 8:00pm even though it cost more than the non direct flights. With no reason other than "unforeseen circumstances", our flight home Monday was cancelled and we were rebooked on a 7:00am flight on 9/29 with a layover in JFK. We were traveling with sick kids coming home from a funeral of a loved one and needed to be at work on Tuesday so paying extra for a flight home Monday was something we had to do. The original direct flights were considerably more expensive than the non direct flights- so I don't understand how Jetblue did absolutely NOTHING to compensate or right their mistake. We will not be booking with them in the future because they are not reliable and they showed no remorse nor did they make any attempt to make things right. The least they could have done was credit the difference in cost of flight because I know our original flights cost more than the one we were rebooked on. Once again- we will not be flying with them in the future and will advise family and friends to be aware of the risk you run when giving them your business. Do better.
The flight attendant was snarky and the flight took off very late. I know it was an issue with air traffic control and the runways in Boston, so not really anyone's fault, but very frustrating, I missed an important meeting because of rgr delay. They didn't offer headphones to watch the TV, but luckily I remembered my own and was able to enjoy watching a movie.
Terrible. We originally booked a direct flight from BOS to MCO on 9/28 at 8:00pm and it was cancelled due to unforeseen circumstances and the flight we were rebooked on was on 9/29 at 7:00am with a layover in JFK. We were traveling with sick kids so leaving at such an early hour was absolutely miserable, and on top of that we all missed work which we couldn’t afford. On top of that- we paid a fortune for our flights to be direct without a layover and the flights with layovers were cheaper so at the very minimum we should have been refunded the difference. With absolutely no explanation or sympathy from JetBlue- we will avoid using them in the future due to the fact they aren’t reliable nor do they correct their mistakes.
Experience with JetBlue was poor. We were originally suppose to fly home on a direct flight on Monday the 28th at 8:00pm and we it was canceled due to “unforeseen circumstances” and we were rebooked on a 7am flight on Tuesday the 29th with a layover in JFK. Traveling with sick kids and waking up at an ungodly hour was miserable, and not only that it caused all of us to miss work. We intentionally flew our Monday on a direct flight and the direct flight was far more than the non direct flights on any given day. There was no compensation provided let alone a reasonable explanation. When you are charging people those type of prices for domestic same coast flights- you should be at least refunding the cost difference of the flights if you are rebooking them on a cheaper flight. I will never fly JetBlue again because they are unreliable and don’t correct their mistakes.
Jet Blue cancelled my flight after I had boarded. They attempted to rebook me for a new flight two days later. I was able to rebook with a different airline, but not until the next morning. As such, I was forced to get an expensive hotel and missed important work meetings Monday morning. I am very disappointed with the customer service and will be pursuing full reimbursement for my hotel cost.
No included food for a 5 hour flight and the entertainment was only accessible if you had wired headphones (not provided). Otherwise though, great and smooth flying and customer service.
They have the most inexperienced / rude flight staff I’ve encountered
I volunteered to let them put my carry on suitcase in the baggage storage area. But when we landed I was told it was being unloaded IN A DIFFERENT TERMINAL! I had to walk (painful for me) a long way to retrieve my bag and my ride had to move from the waiting area they were in to a totally different one. Not happy.
There is was everything terrible all my flights was delayed so I missed my connection flights
The guy sitting in front of me kept pushing hard his sit against my legs… very uncomfortable
Food was horrid. In my opinion inedible. They did offer some sorbet and one small dish of fruit. Stewards were super stingy with water, coffee, etc.
I believe my father had a good flight. What was not good, was the associate who helped us during Step 2 of check-in. After getting his boarding passes and bag tags, we proceeded to Step 2 where we were met with Carol. This was around 3:15-20pm at Phoenix Sky Harbor. She weighed my father’s checked bag which was 2lbs over, she recommended removing a pair of jeans to correct this. My father asked/joked if “she could just let him go” and she fairly rudely responded something along the lines of, “I don’t own the airline so no I can’t do that”. From this point on I just want to assume she was having a bad day. I spent my life raised in a business and front-facing customer service so I understand previous clients can make you feel irritated. How she continued to act leads me to believe she was really careless about her job or racially biased/straight-up racist. After we moved the 2lbs to his other bag, she told us she believed he would need to claim his bag at his connecting flight in Hong Kong, before it could go to his final destination, Malaysia. This thoroughly confused us as we are fairly frequent international travelers and 95% of the time the bag is sent to its final destination without this requirement. Last time we traveled to Malaysia was less than a month ago, so again we’re fairly confused. Multiple times she used a fairly aggressive tone of “I know what YOU THINK, this is what I believe”. The multiple “YOU THINK” as if we didn’t understand what she was saying was rude and insulting, and her tone came along with a insincere smile, hence the feeling of she was racially biased. Despite the fact that she might have been having a bad day previously, it is AA’s airline’s duty to train their employee about international bag protocol, as clearly AA is a major partner of internationally traveling airlines. Carol made the experience overall unenjoyable sending my father off and made us both question AA’s training of their employees.
Once again the staff of American Airlines is kind, helpful, efficient, and professional.
Paid for wifi but it didn't work once. Seats were incredibly cramped and passengers sitting in front was reclined the entire time and staff did nothing
No food. I paid over $1.000 for my ticket for nuts and espresso beans.
I'm not sure American is capable of on-time arrivals and departures. When you land at ORD, you almost always get held on the tarmac because your gate is still occupied. I may have missed my connection, but that ended up up being significantly delayed as well. Once again, I finally got home well after midnight.
Turn on the heat. Flight was way too cold from Arizona to Chicago.
Overall pleasant was delayed and caused transportation issue when landing
The staff at the check in counter was so rude. Made you feel Incompetent
Frontier scheduled a 40 minute connection in DEN. What they failed to mention was that they “close the doors” 20 mins prior to departure, which means you only have 20 mins. Not enough time. Possibly against DOT regulations. Filing complaint.
The bag check, flight check-in, and onboard experience convinced my wife and me that we will actively go out of our way to avoid flying Frontier Airlines in the future. At bag check, we were informed that check-in could only be completed via the Frontier mobile app. Unfortunately, the app was extremely frustrating—sending us through repetitive, confusing loops that repeatedly forced us to decline add-on services with nearly every click. While most airline apps upsell, this one felt intentionally exhausting. As the process dragged on, we became genuinely concerned that my phone battery would die before check-in could be completed. We approached the bag check staff—who were standing together talking—and explained both our frustration and our predicament. They laughed. Later, my wife described the interaction as “gaslighting,” which felt accurate. We were then informed it would cost $25 per person simply to have our boarding passes printed. From that point forward, the tone of the experience was consistently hostile. The bag check employees were condescending and combative, behaving more like bullies than customer service staff. Unfortunately, that same attitude continued onboard. One flight attendant argued with me when I attempted to stow my backpack in the overhead bin. I explained that we had each paid $75 to check our bags specifically so we would not need to use carry-on space and could have adequate legroom. She demanded to see my ticket, pointed out that it said “no carry-on”—which I acknowledged—and I reiterated that this was precisely why we paid to check our bags. Her response was, “I don’t make the rules.” She then walked away, but not before asking if I “truly wanted to fly back to Chicago today?”—an unnecessary and unmistakable threat. It is also worth noting that despite booking our tickets together in the same transaction, we were not seated together. Upon our return to Chicago—where we could once again sit together—we compared onboard experiences. We both remarked on how unhappy the flight attendants appeared and how each of us was separately asked whether we would like to purchase a beverage. We declined. At no point was water mentioned as an option, leaving us with the clear impression that even water came at a cost—or that complimentary water, if available at all, was deliberately left unmentioned. Overall, the experience was shocking and deeply disappointing, but it was also a profound learning experience—one we will not forget and will not repeat. -Steve
Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.
Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.
It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.
Horrible. I would never fly Frontier again. The booking process is tricky at best, but fraudulent in my opinion. Frontier customer service did nothing to rectify my purchase -- I ended up paying more than double what I could have gotten from other airlines and nearly triple what I thought I was buying from Frontier. Their booking practices are unfair to the consumer.
I think Frontier was very good at communication. Their app worked very well. Loading was great and the flight was nice and easy.
Early arrival. Great landing. Pilot updates. Too cold in plane.
My experience with the phoenix airport was terrible, the personnel lay the ticket counter charged me for a carry on that fit in the carry on size box, and the two women I spoke with were terribly rude and not willing to help.,,, there was one lady “candy” on the flight crew that was amazing and is the only reason I stayed on the flight at all, because the other stewards helping people to get seated on the plane were terrible
