Hey folks, if you've already booked a flight with Sun Country Airlines and now want to bring along an extra friend or family member, you're probably pondering,
How do I add a traveler to an existing reservation? I've been in that spot myself—planning a group trip to Las Vegas and realizing at the last minute that my cousin wanted in. Sun Country's system isn't set up for simply tacking on another passenger online like some airlines, but there are ways to handle it without too much drama. If you're unsure, their support at
(844) 734-0813 can give you the latest on policies. Let's unpack this step by step so you can get everyone on board.
Understanding Sun Country's Reservation Policies
First off, Sun Country doesn't allow you to directly add a new traveler to an existing booking through their website or app. Reservations are typically tied to the original passengers, and adding someone new often means creating a separate booking for them. This is common with many low-cost carriers to keep things simple and fares low. If your original booking was for a solo trip or small group under 10 people, you'll likely need to book the additional ticket separately on suncountry.com. That way, you can search for the same flights and try to match itineraries. I did this for my Vegas adventure, booking my cousin's ticket right after mine, and it worked out fine since fares hadn't changed much.
Booking a New Ticket for the Additional Traveler
Head to suncountry.com and start a fresh booking with the same flight details as your existing one. Enter the new traveler's info—full name matching their ID, birthdate, and contact details. You can pay with your card even if it's not in their name; Sun Country is flexible there. Keep in mind potential fees like the passenger interface charge ($22 per segment), which applies to online bookings but can be avoided if you book at the airport. Once booked, note the new confirmation number. If fares have gone up since your original booking, the new ticket might cost more—something I wished I'd anticipated when adding that extra person.
Linking Reservations or Seating Together
After booking the new ticket, you can try to link the reservations for easier management, like seating assignments or changes. Log into "Manage My Trip" on the website using your original confirmation code, but for linking, it's best to call Sun Country's reservations team. They can often associate the bookings so you can request seats together or handle group check-ins. When I called
(844) 734-0813 for my group, the agent was helpful in noting the linked reservations and even suggested better seats for us all. Just have both confirmation numbers ready, along with passenger details.
Special Cases: Groups or Modifications
If you're adding multiple people and your total group hits 10 or more, Sun Country offers group travel services, which might allow modifications to an existing booking. For these, contact their group department—details are on the website, or ask when you call the main line. For smaller additions, if your original booking is far out (over 60 days), changes might be fee-free, but adding a person isn't a standard "change." Name corrections or updates are possible online or by phone, but full additions aren't. Always check for availability; if the flight's full, adding anyone could be tricky.
Potential Fees and Tips to Save
Watch out for change fees if you're adjusting anything on the original booking—like $39–$69 per person if under 60 days out. Booking the new traveler early helps match fares and seats. Sign up for Sun Country Rewards to earn points on both bookings. I recommend calling
(844) 734-0813 early in the process to confirm if linking is possible and to avoid surprises like mismatched fares. If you're at the airport anyway, consider booking the add-on there to skip that interface fee—saved me a bit on a previous trip.
What If Plans Change Further?
Once added (via new booking), manage everything through "Manage My Trip" for seats, bags, or check-in. For cancellations, you get a full refund within 24 hours if the flight's over seven days away. But if you need to tweak the new addition, the same rules apply. My tip: Double-check passport or ID requirements if international, as adding someone last-minute can complicate that.
Adding a traveler with Sun Country requires a bit more legwork than some airlines, but it's doable with planning. Whether it's a family addition or a buddy joining the fun, getting it right ensures smooth travels to those sunny destinations.
