Flying with a lap infant on Alaska Airlines is free for domestic itineraries within the United States, Canada, Mexico, Costa Rica, and Guatemala, provided the child is under two years old. However, navigating oxygen mask restrictions, specific international taxes, and baggage allowances requires careful planning before you head to the airport.
Knowing the exact policy details prevents surprises at the gate. Whether you're booking your first trip with a newborn or planning an international getaway, here is everything you need to know about flying with a lap infant on Alaska Airlines.
Understanding Lap Infant Eligibility and Age Limits
An infant must be under the age of two for the entire duration of the journey to qualify as a lap child. If your child turns two years old during your trip—including on the return leg—you must purchase a separate seat with a valid ticket for all travel on or after their second birthday.
Alaska Airlines doesn't enforce a minimum age limit for newborns, but pediatricians generally recommend waiting until an infant's immune system is more developed before flying. If you are traveling with an infant and you are under 18 years old, you must be the parent or legal guardian to add the lap infant request to the reservation.
Domestic vs. International Fares and Taxes
For domestic flights within the U.S., infants under two fly completely free on an adult's lap. This zero-fare policy also extends across nearby international borders to Canada, Mexico, Costa Rica, and Guatemala.
For other international routes, long-haul flights typically require 10 percent of the accompanying adult fare plus applicable local taxes and user fees. Depending on the specific departure country, you might encounter local government or immigration taxes ranging from $18 to over $50 USD.
Step-by-Step Instructions to Add a Lap Infant
You can easily add a lap child to most domestic itineraries online during the booking process or through your account under manage reservations.
- Book the adult ticket first or select passenger details including the infant during initial booking if the digital portal allows.
- Contact customer service if you are booking an international route or if the online system fails to attach the infant correctly. International lap infant tickets must frequently be processed through the contact center or at the airport.
- Verify documentation by bringing a government-issued birth certificate or passport to prove the child's age upon check-in.
Seating Restrictions and Oxygen Mask Layouts
You cannot sit just anywhere when holding a baby. Federal aviation safety regulations limit lap infants based on oxygen mask drop-down locations.
- Row limitations: On most Boeing 737 aircraft variants flown by Alaska Airlines, only one lap infant is permitted per row across the aisle due to fixed oxygen mask counts.
- Exit rows: Lap infants are strictly prohibited from sitting in exit rows or the rows immediately preceding or following them.
- First class limitations: Lap infants traveling in the First Class cabin do not receive complimentary meal service, so you must pack enough food and formula for your baby.
Stroller, Car Seat, and Baggage Rules
Traveling with an infant means hauling extra gear. Fortunately, Alaska Airlines maintains generous policies for baby equipment.
You can check a stroller and a car seat free of charge. These items can be checked at the ticket counter or gate-checked right before boarding. Stroller-wagons are also permitted as checked items provided they collapse under 35 pounds and 90 linear inches.
Keep in mind that a lap infant does not receive a separate carry-on luggage allowance. Your baby's diaper bag counts as the accompanying adult's personal item or carry-on bag.
Common Mistakes to Avoid
- Assuming international is always free: While Mexico and Canada are free, other international routes trigger a 10 percent fare plus taxes. Always check pricing ahead of time.
- Failing to bring proof of age: Gate agents can request a birth certificate or passport. Traveling without verification can cause severe boarding delays.
- Ignoring the birthday milestone: If your child turns two halfway through a vacation, forgetting to buy a return seat violates safety rules and forces last-minute airport purchasing.
Frequently Asked Questions
Can my lap infant get their own empty seat for free?
If the flight isn't full, gate agents may allow you to use an adjacent empty seat for an infant car seat. However, airlines cannot guarantee empty seats, and you must purchase a ticket if you want a guaranteed separate space.
What documents do I need to show for my lap infant?
Carry a government-issued birth certificate for domestic travel. For any international itinerary, your infant must possess their own valid passport matching the destination country's entry requirements.
Are bassinets available on Alaska Airlines flights?
Alaska Airlines does not offer bulkhead bassinets on its fleet because of aircraft configurations. You must rely on holding your baby or utilizing an approved car seat in a purchased seat.
Can I use a car seat if I decide to buy a separate seat for my infant?
Yes. If you purchase a ticket for your child, the car seat must be FAA-approved with a clear label indicating compliance, and it cannot be placed in an exit row.
