Flights from Louisville to North America: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Louisville to North America 
Verified travelerFlew with American AirlinesSDF-CLTMar 2025
More time should be given between connecting flights. Large distance to travel from Concourse C to Concourse B.
Mike & DebbieFlew with SouthwestSDF-HOUMar 2025
TSA screening backs up over lunch time. A smaller area for Screening slows things down.
RoyceFlew with Spirit AirlinesSDF-FLLJan 2025
Don't get there earlier than two hours, otherwise you'll be waiting to check your bags in Louisville. It's just a tiny airport.
TinaFlew with DeltaSDF-ATLOct 2024
Arrive early so you don’t feel rushed. Mind your assigned zones. I know people want to get onboard as soon as possible because of overhead compartments, but plan ahead in case you need to gate check your bag. And pack your patience. I know that sounds cliched but it’ll help.
Verified travelerFlew with Alaska AirlinesSDF-ORDApr 2024
If flight gets delayed. Be sure to ask the airlines you traveled with, to rebook the next available flight immediately.

There is no lounge in Louisville. Two mediocre restaurants, Chili’s and Coal

Bring back peanuts Take our drink orders when were all seated, especially after you switch to assigned seating.

Staff was far less than helpful at all times. Departure and arrival times mean nothing to Southwest. Extremely disappointed, will never fly with them again, and I’ll be sure to share my experience with all.

It is southwest seat was ok. Not the most comfortable seat

I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

Plz don't take away free bags and free seating

The seats were a bit cramped and worn, but otherwise okay.

I would have liked to arrive on time - not 5 hours late!

After a 3 hour layover in Denver my flight was delayed over 5 hours! No explanation; no assistance; no offer to provide compensation; no one at Southwest was willing to offer any assistance. 8 hours in the Denver airport - ridiculous!

It was a perfect flight in all aspects! Both legs!

Food from the flight from Atlanta to Santiago was very poor..

Flight was delayed due to weather. Crew did a nice job of making us comfortable. No complain complaints.

Our bag was lost so that made unnecessary chaos On our trip

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

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.

Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

A bit rush for transit. Food and entertainment are not available

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

Multiple delays and not straight answer from the United team

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Was a normal flight but it was delayed, and there wasn't an explanation.

In flight connectivity (via T-Mobile) was often not working.

Pitch was very small. Knees were on the seat back in front of me.

really bad they refused to check in luggages that I had purchased, even showing them the transaction receipt from british airways app the staff in miami was MEDIOCRE

Several delays. Next flight was worse. Did not arrive home until 2am PT

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Spirit is by far the worst airline to travel with, period. Seats are cardboard, flight attendants need anger management and if you ask for water, you’re basically a criminal. I don’t care how much it costs but I will travel with an airline who actually cares about their customers. Oh and one more thing, the next time your gate agent puts his foot on someone’s baggage's scale, I hope they get what’s coming next, a viral video of your scams. You suck Spirit, do better.

I mean, it’s Spirit. But it was frustrating to have our flight canceled, get bumped to a later flight, and then Spirit was unwilling to check our bag until 4 hours before our flight… tell us we could not sit in the waiting area’s chairs… and really negative experience getting checked in and dropping the bag.

Not having it be changed after we bought the flight tickets from a direct flight getting in at a reasonable time to a connecting flight red eye of 9 hours, so that we would lose our 35 dollars in nonrefundable insurance would've been great! Our country really does need low-cost carrier options, but this type of "service" ain't it. Fortunately, had a little better success with them flying to and from San Juan PR last month at least.

All was good expecting the seats need a bit of cushion. Besides that I can’t complain.

You get what you pay for, and the flights went smoothly. There’s no reclining chairs, no screens, And there isn’t always wifi, but the plane was clean and staff was friendly and the takeoff/landing were smooth.

The only positive is that the flight made it both ways. Getting charged for every little thing after the cost of the ticket itself is comical, considering how the plane and services are as bottom-tier as possible. The self check-in kiosks are useless. It’s nice to think that you can print your boarding pass, tag your checked bag, and then just drop it off. But no, they still make you go through the line once you finish- what’s the point of the self check-in then? Any questions for the staff seem like the biggest inconvenience and were met with condescending responses. This was my first and now last time ever flying with Spirit. After all the extra costs, subpar plane and staff, I see no value. I’d rather drive the 13 hours than give Spirit another dime.

The flight was fine however what started as a reasonable priced ticket could have become an overpriced ticket with additional charge for carry on as well as checked bag $79 per bag per person each way. Additional charge for choosing one’s seat, additional charge for beverage and snack, we were on what was described as a new plane yet there were no audio/visual on the jet. A bare bones service but not at a bare bones price. Will think twice before flying Spirit again. 😕

Flight was delayed a bit, but that was expected (and updated), so really not bad at all for the price. Could’ve used one less email asking me to upgrade my seat; otherwise no significant complaints

I love Spirit. New aircraft, great cabin service, the airfares are low cost which helps me visit my hospitalized daughter anytime I can without paying a fortune.

Flight was 2hours late they had no crew or the pilot.
