Sun Country Airlines Missed Flight Policy is generally strict, as the airline treats most missed departures as a no-show, which can result in the loss of the ticket’s value and cancellation of any remaining segments on the booking. If a passenger misses their flight due to late arrival at the gate, traffic, or security delays, Sun Country does not automatically rebook or refund the ticket, especially for non-refundable fares. However, travelers who contact the airline immediately after missing a flight may be offered rebooking options on a later flight, usually by paying the fare difference and any applicable fees, subject to seat availability. Exceptions are limited and typically apply only in cases of airline-caused disruptions or special circumstances, so acting quickly and understanding the fare rules is essential to minimizing losses.
