Though its open seating policy has caused many a family to question the “family friendliness” of Southwest (you know, after all of the earlybird check ins and A-list flyers with boarding positions ahead of you have chosen their seats and filled the corresponding overhead bin), especially for those flying Southwest Airlines with a baby or toddler, there is still one big reason Southwest Airlines deserves the praise of some family travelers: Southwest is one of the last U.S. airlines offering a significant discount for infants flying in their own seats. In some cases, a child fare may also be available.
We’ll look at that in more detail and address some other considerations for parents flying with babies and toddlers in this post as part of our Need to Know Airlines series. UPDATED for 2018.
First, infants under 2 years can fly free–but only with proof.
As with other U.S.-based airlines, children under 2 years may fly free on domestic flights, but you must be prepared to show proof of your child’s age. Even if you’ve managed to board with your lap child before without showing ID, you should not expect that to be the case every time–and especially not if you’re flying Southwest Airlines with an infant.
Southwest requires all lap children (lap-held infants) flying for free to have a Boarding Verification Document or BVD. Note: This is not the same as a boarding pass. Even if the rest of your party has checked in online, you will need to see an agent at the counter to present your lap child’s proof of age–a certified birth certificate, birth record, or passport–in exchange for the BVD.
Yes, you CAN still get an infant fare from Southwest.
Many parents I speak with have no idea the discount for children under 2 years still exists. That’s because the infant fare for seated children under 2 years old is not advertised by Southwest, nor is it available for booking on their website or elsewhere on the web. But if you’d like your baby under 24 months to fly in her own seat–and car seat or CARES flight safety harness, here’s how you can get it.
How to get the Southwest Airlines infant seat fare:
- You must call Southwest Airlines customer service at 1-800-I-FLY-SWA (1-800-435-9792) to purchase the discounted fare for your flight.
- Your child under 2 years must fly in an FAA-approved CRS (child safety seat/car seat) during your flight (not over 16″ wide is recommended, some recommended car seats for travel here and tips for fitting car seats in airplanes here).
- You must have valid proof of your child’s age (under 2 years) at check in to prove eligibility for your child. A certified birth certificate, birth record, or passport is recommended.
- You must have (or create) a Rapid Rewards accoung number for your child in order to use online check-in for his or her reservation (see more in “Why and how to age verify your infant” below).
Why the Southwest Airlines infant fare may not be your best deal:
That said, here’s why the Southwest Airlines infant fare may not be your best deal when booking a seat for your child. These infant fares have no restrictions and are fully refundable–a good thing in some respects.
But as you might guess, if you’re booking a great bargain on deeply discounted adult fare seats with Southwest (eg. a Click n Save special offer), that fare may actually be cheaper than the infant fare for your flight, in which case you may prefer to book an extra seat for your child at the discounted adult price (and still be sure to bring your child’s FAA-approved car seat for the flight).
Still, it never hurts to ask what the infant fare for your flight would be to be certain.
Why and how to age-verify your infant with Southwest Airlines:
The first time you fly Southwest with an infant discount, you will need to check in at the ticket counter and present valid ID, as mentioned above. A certified birth certificate, birth record, or passport is recommended. But at this time, the Southwest agent will be able to add a “verified age” to your child’s Southwest Rapid Rewards account.
For future bookings, you’ll be able to do online check-in for your whole family using your Rapid Rewards accounts, even when flying with an infant fare. What’s that? You don’t have a Rapid Rewards account for your baby? Follow this link to create your child’s account at the Southwest Airlines website.
So can you really get a child fare with Southwest?
Not bloody likely (or likely to be more than the discount fares). But if you’re looking at full-priced fares for the adults on your trip, it may be worth at least making the call to find out. Again, just like Southwest’s infant fares, you’ll have to call the airline to see if a discounted fare may be availalble for children ages 2 years through 11 years: 1-800-I-FLY-SWA (1-800-435-9792). Age verification will also be required at the airport.
Southwest Airlines baggage policies for babies:
Remember, first checked bags up to 62 inches (measured as length + width + height) still fly free on Southwest–for ticketed passengers, which certainly helps when you’re flying with 3+ people.
Infants and babies flying on an infant fare are considered ticketed passengers with full rights to the standard baggage allowance, including one carry on bag and one personal item.
Lap-held children flying for free are not entitled to a free checked bag on Southwest, though checked travel strollers and car seats do fly free with this airline.
