How Frontier Airlines checks onward tickets at check-in
Frontier Airlines (IATA: F9) serves high-volume leisure routes from Orlando (MCO), Miami (MIA), Atlanta (ATL), Denver (DEN), and San Juan (SJU) to Mexico, Costa Rica, the Dominican Republic, and the Caribbean. Because Frontier relies on contracted ground handlers at both US gateways and international stations, agents strictly follow the automated TIMATIC prompts in Frontier’s GoNow departure control system.
When you fly Frontier on a one-way ticket to Costa Rica (SJO), the Dominican Republic (PUJ, SDQ), or Mexico (CUN, PVR, SJD), the system flags your reservation for mandatory document verification. You must show a confirmed outbound flight reservation departing the destination country within the allowed tourist window, alongside any required digital health/customs forms (such as the Dominican Republic e-Ticket).
Note that Frontier strictly closes check-in and bag drop 60 minutes before international departure—meaning if you are turned away at the counter to book an onward ticket, you have very little time before the flight locks.
Why Frontier Airlines Online Check-In Blocks Mobile Boarding Passes on One-Way Flights
Frontier’s mobile app blocks boarding pass issuance for one-way international travelers whose destination requires onward-travel verification under TIMATIC. Instead, the app displays a counter verification notice requiring you to visit a Frontier agent more than 60 minutes before departure.
Frontier Airlines routes where onward tickets are checked most strictly

How an OnwardTicket.us PNR clears the Frontier Airlines check-in counter
