KAYAK’s top tips for finding a cheap flight from Austin to St. Louis

  • Typically, flights from Austin to St. Louis depart from Austin Bergstrom International Airport (AUS) and arrive at Lambert-Saint Louis International Airport (STL). Dubbed AUS, Austin Bergstrom is located approximately 5 miles southeast of downtown Austin, Texas. AUS is a hub for Allegiant Air and it serves several popular airlines on this route that include American Airlines, Spirit Airlines, and Alaska Airlines. The airport features two passenger terminals; South Terminal and Barbara Jordan Terminal.
  • Make sure to arrive at AUS at least two hours before your scheduled flight departure. Usually, the current wait time at AUS is around 25 minutes on average and this is the time it will take you to go through all the security checkpoints which are located in both terminals.
  • Alternatives to AUS include Austin Executive Airport, Bud Dryden Airport, Breakaway Airport, Georgetown Municipal Airport, and Elgin Intracontinental Airport. All of these are considered smaller airports compared to AUS, where most passenger flights to various destinations happen.
  • If you are traveling through AUS without checked luggage, you can save your time by skipping the airline ticket counters and proceeding to security screening checkpoints. Use the upper curbside and lower curbside for drop-off through elevators and escalators at the Lower Level. You may also take advantage of the self-service flight check-in kiosks inside the terminal to save your boarding time.
  • Choose the most convenient transportation means from Lambert-Saint Louis International Airport (STL) to downtown St. Louis. Remember, STL is about 15 miles from the St. Louis city center, so using a taxi or a bus should be a cheaper option. Ride Share Services, Shuttle Service, Limousine, services, and MetroLink are additional transportation means and you can find them just outside the passenger terminal.

I didn’t know that food needed to be ordered ahead. Please include this in the reservation information. Overall, very good experience.

Plane hit turbulence diverted to Houston. We'll probably get in after 3am

Cabin crew very friendly and pleasant. Flight left late but we didn't know why. Alaska Airlines app was not user friendly -- app wouldn't let us upgrade our seats, but no indication if flight was full. We wound up having to call the airline to request an upgrade and we were told none was available. Waste of time. Baggage retrieval was easy.

Full flight where I had another passenger sitting in middle seat who said that he had lost 250 lbs from 500. The stewardess on exiting the flight advise me that I was going to receive a refund. I thought she was talking about another passenger. The stewardess saw that to make him comfortable I had lifted the armrest and flew for 5 hours to Seattle from Reagan DCA with a portion of his body on my seat. I survived. I flight to remember!!!!

the flight was delayed almost 3 hours and not one time was we told that it was delayed or why. I had asked one of the crew members why it was delayed, 20 minutes after the flight was supposed to take off, and was told that they had no idea what was going on and that they had not been told anything. this is FRIGHTENING!!!! No excuse!!

Given incorrect gate upon check-in, corrected by the gate attendant, D6 rather than D5, minor inconvenience. As with the previous flight, passengers were admonished to voluntarily gate-check carry-on luggage with the statement that those in the last boarding group would have no choice but to do so. If the Boeing 737 MAX8/MAX9 doesn't have room for carry-ons it's an interior design flaw on the part of Boeing. Posting an advance warning would be helpful, such as "Boeing 737 MAX planes feature limited carry-on space. Please be aware." SFO's amenities and TSA much better than MCO's. Crew was amazing! Brought my own food because Alaska's onboard selection has soy in everything. Beverage service was excellent. This was the first and last trip with Alaska after the previous flight's issues. It's no reflection on the crew of this flight. They were great.

Flights were on time. Check in was fine. Crew members were pleasant.

The boarding gate is literally just an aisle to the concourse. There is no seating and it's shared with several other airlines. It's crowded, hot, and standing-room only. It's difficult to hear gate announcements over the PA system with too many other carriers crammed into a small space. I've enjoyed flying AA in the past on the west coast, but the BNA single gate experience is horrendous! Never again from BNA to SEA with AA.

I would have liked it to have been easier to order food for the flight. My son was not happy with the snack pack I bought him and it was a very long flight for a little boy to go without food.

It was a partial full flight. But even with a spare seat it was hard to get comfortable More on me being a wide body probably

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

They were an hour late and they didn’t have my wheelchair for me

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

There was a group of school age passengers that were very loud and unruly with their chaperones were no where to be found.

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

I liked everything about the flight. The service was excellent!

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

The flight was short. However, my bag was delayed and was put on another flight.

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

Missed the flight because of them and up geting a rental car

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

I arrived to the airport 2 hours before my American Airlines flight was scheduled to take off. I have TSA pre-check. The airport was crazy packed when I arrived. After momentarily standing in the pre-check line, the TSA agent said that I am not pre-check. Of course I said that I am because I entered my KTN number on all my traveling sites and programs. I had to get out of line and go back to the AA counter to discover that American Airlines did not add my KTN to my boarding pass. I had to call TSA to find out my number, then have AA enter it onto my boarding pass. The emblem would not load onto my boarding pass. By this time, I decided to use my Clear in order to get through TSA but the line was ridiculous long. By the time I made through TSA, I missed my 11:08am flight and was re-booked for the 5:30pm. This is after the AA employee told me I should have gotten to the airport early. AA use to be a dependable airline not I use them only if I have too.

Flight from SBP to DFW 1. They rerouted us through PHX 2. Delayed flight out of SBP for 3 hrs so we missed our connection Downgrade on rerouted flight. Back of the plane, center seats, didn't sit together 4. Return flight out of DFW same exact thing. Delayed, missed connection, Downgrade + they lost our luggage! A complete mess.

Do not eat the bagel! Otherwise, good albeit late, breakfast in first. Boarding downgrade only because flight was delayed due to plane change due to undisclosed problem with original aircraft. I did not use entertainment.

9hrs delay and didn’t provided anything until after flight landed $75 voucher for fiuture travel no meals or anything.

It was ridiculously hard to check in for the flight, and Frontier charged us a LOT of money to have a carry on suitcase, and then told everyone we could not carry on bags and had to check them through at the gate, and didn't refund the extra money we paid to have the suitcase as carry on.

I had a terrible experience with Frontier. I arrived before the 60 minute cut off and was told that Frontier has a two hour window for bags. I was then told the next available flight wasn’t until the end of the day (I had booked a 6am flight). I took a look around and saw other people being told that they could not board their flights or that they had to pay additional fees. I opted to rebook on American Airlines. There’s absolutely no straightforward way to contact Frontier, so this ticket was a complete waste of money. Oh - and the kicker is that the lady lied about the two hour cut off.

Frontier won’t help you at the airport without paying $25. Carry on was $75. Then you get on the plain and every beverage or snack is also a charge. Seats are hard and real packed in. I would never fly them again.

Worst experience I have seen. The flight was cancelled without any reason.

My experience with frontier staff at the Denver airport was absolutely horrible. The manager on duty was even worst if was the worst experience I have ever had, I have never been treated so poorly as a customer in my life! The staff was extremely rude, eye rolls and attitude and then refusal to help me at all. I wish I could never fly frontier again that’s how horrible it was!

The Frontier app wasn’t working. So I could not pay for a carry on the week prior to flying. They charged me 99$ at the gate to carry on a duffle bag.

Good for the price. My only complaint is that the pilot should keep the air flowing while passengers are waiting to getting out of airplane.

Plane could have been more on time. More leg room .

I arrived 1 hour prior to boarding, and they said I was too late for a domestic flight. First time I heard that :-(
