FAQs for booking Orlando to Ontario flights

  • What information should I provide to reserve a flight for a minor?

    United Airlines asks for the names, contact details, and addresses of the adults who will bring your child to MCO Airport and meet them at Ontario International Airport (ONT). These can be legal guardians, parents, or responsible adults. Pay the Unaccompanied Minor service fee during the online reservation or at the check-in counter. Avoid paying tickets via telephone since they cost more.

  • Will I pay extra for pre-assigned seats when traveling with children?

    When children and an accompanying adult are on the same booking, Frontier guarantees adjacent seats to allow the family to sit together in their chosen class of service. You will not pay a fee for these pre-assigned seats. Avoid changing your seats once your family has been assigned adjacent seats.

  • Can I carry two pets when flying from Orlando to Ontario Airport?

    You may have two pets aboard a Delta flight, provided they are of a similar breed. If you bring two cats, they should be ten weeks to 6 months old, fit comfortably in the kennel, and be compatible. You will not be charged double since they count as one baggage.

  • Will I get stowage of my assistive devices?

    American Airlines does not count mobility and medical devices as carry-on baggage. You can put your walker, cane, footrests, and CPAP machine in the under-seat or overhead stowage spaces. If it's too bulky, it will have to be checked. If you have a battery-powered assistive device, contact the airline's Special Assistance number to confirm your battery is suitable for air travel per FAA guidelines.

KAYAK’s top tips for finding a cheap flight from Orlando Airport to Ontario

  • Southwest Airlines presents stopovers in cities like Denver (DEN), Austin (AUS), Dallas (DAL), and Chicago-Midway (MDW). American Airlines has two route options through Dallas-Fort Worth (DFW) or Phoenix Airport (PHX) as layover destinations. United Airlines connects flights in Denver (DEN) or San Francisco (SFO). Frontier Airlines and Delta Air Lines offer Atlanta (ATL) as a possible stopover, while JetBlue stops at John F. Kennedy International Airport (JFK). Alaska Airlines includes Seattle (SEA) as a layover destination, and Spirit Airlines offers a stopover in Dallas-Fort Worth (DFW).
  • Southwest Airlines provides four fare categories: Wanna Get Away (non-refundable but reusable as flight credit), Wanna Get Away Plus (non-refundable but transferable to a same-day standby flight), Anytime (refundable and reusable), and Business Select (refundable and reusable). If you must cancel your flight, do so at least 10 minutes before departure. There are no flight change or cancelation fees; fare difference applies if you rebook a higher-fare flight.
  • Before checking in online with Spirit Airlines, find out whether you are eligible. This option is available for all US citizens, but non-citizens from other countries must check in at the Orlando International Airport (MCO) ticket counter. Other exemptions include unaccompanied minors, guests with infants and pets, passengers in a group reservation (10), military personnel, and those who pre-book extra seats and space for special items.
  • Fly with the greenest airline in America – Alaska Airlines – one of the most fuel-efficient airlines with modern aircraft and flight optimization. In May 2022, it had the lowest rate of CO2 emissions per seat per mile of any full-service carrier (128 g). A high seat density is the hallmark of Alaska Airlines' 737s. With 23 of the 737 MAX 9 models in its fleet, it offers improved efficiency.
  • You don't have to sit in the regular Economy or Core seat for your flight on JetBlue with 32 inches of pitch. Instead, choose Even More Space with a 35-inch pitch in the first five front rows and 38" in the two exit rows. You'll also be entitled to early boarding, expedited security checks at MCO Airport, and overhead storage.

Kayak could’ve posted the correct gate number. Almost missed my flight.

Slow boarding, limited food and drink portions. Bad delays and turbulence

The first time I flew in the extra legroom section. It was difficult to notice a difference. I had bad luck with my neighbors. The crew was okay. Southwest has reduced the live TV options.

No gluten free snacks. Seats felt worn or bare bones even though it was a new 737 MAX 8.

The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.

Not having a five hour delay with little notice! The crew was very kind, though, and just as tired as we passengers were. The flight didn't depart until nearly 1 am...and no reason was ever given.

This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

Communication about the delayed flight was poor. We were told to move gates three times but that was bad information. We went from gate 128 to gate 126 and then to gate 123 and back to gate 126. Communication about the delay was bad. Ended up being 1 1/2 hour late getting home.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Service was professional and quick. Premium economy seat was comfortable given the class

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

It was so much better than expected, Ohare is not such a pleasant experience but American Airlines with the new, clean aeroplane and free Wi-Fi was outstanding and the crew so pleasant and helpful.

Was put into a seat right behind the toilet that had no entertainment possible but did have plenty of leg room over noisy part of plane.

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

My original flight got delayed day of so I had to rebook it from one layover to two layovers. The flight also left earlier which was a slight inconvenience but manageable. Then my first connection flight got delayed 3 separate times for a total of 2 hours delayed, causing me to miss my second connection flight back to Santa Barbara. Now, because of this missed flight, I am missing my college classes that I pay for.

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

To have arrived on time and not 3 hours late after having already spent $100 to change to an earlier flight, only to arrive back home close to the original flight time.

American Airlines is a miserable experience. It is predictably miserable, in the sense that every time I fly American, I brace myself for the certainty that it will be unpleasant and uncomfortable. But it is unpredictable in the sense that I never know if the flight will be on time or delayed nine hours (both happened to me this week). I never know if I will be able to sit in the seat that I selected when I purchased the ticket or if I will be told by Customer Service (!!!) that I must relocate from first class to a seat in the back of the aircraft with no explanation (both happened to me this week). Will the food be frozen and half defrosted, or scalding hot? Will the drinks be warm? Will the flight attendants be surly and mean? Will the toilets be cramped and foul? Will the seats be narrow and uncomfortable? Will there be a real electric outlet at the seat, or just an unreliable USB-2 port? Will there be enough seats in the boarding lounge or just a few? Will the boarding process be smooth and efficient, or will the gate agents mess it up and delay it needlessly for 30 or 40 minutes? Will the catering and cleaning crew be prompt or will they take an extra 30 minutes? Will the brakes on the aircraft work properly, or will the pilot delay takeoff for four hours while the ground crew attends to what can only be described as routine maintenance that should have been done the night before? I've eexperienced every one of these unpleasant things this year, 2026. The only thing I can reliably count on is that American will find a new way to make the experience of flying as miserable as they possibly can.

Wifi was spotty. Tray table was very dirty when I sat down.

The WiFi would not connect enough for me to do my actual work. It permaspooled, disconnected, said it was connected, then wouldn't open an email... it was frustrating. I am not a tall person, 5'4" - and I felt cramped with little room to reach into my bag under the seat in front of me. I feel sorry for anyone taller than me having to fly. the one positive thing I will add, is the overhead bins are roomy enough to manage more bags than other carriers.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Flight got delayed for 5 hours no good explanation was offered ;(

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

i was unable to check in the flight. refund requested

I think Frontier was very good at communication. Their app worked very well. Loading was great and the flight was nice and easy.

The experience was good. No frills but I got there safe and sound and on time.

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.

After boarding and un-boarding twice over 6+hours, the flight was canceled.

Severe turbulence. Captain never came on to reassure passengers after things settled down.

Boarding in Orlando was not good. Giant mob at the gate, should have been lines.
