Quick answer: Frontier does not run an unaccompanied minor programme. It has not accepted children travelling alone under the age of 15 since November 2018, and any child under 15 must be on the same reservation as an accompanying adult. There is no supervised option to buy, at any price, on any route. From 15 a young person may fly on their own, but with no escort or handover service attached. If you need a child under 15 flown somewhere, call a travel expert at Fond Travels on +1 (323) 800 6001 and we will find a carrier that will carry them.
This catches families out because most large US airlines do run a supervised programme, and parents reasonably assume every airline has one. Several of the low-fare carriers do not, and a search that sorts purely on fare will put you in front of one of them.
What the rule actually says
- Under 15: cannot travel alone. The child has to be on the same reservation as an accompanying adult.
- 15 and over: may travel alone, as an ordinary passenger.
- No supervised service exists for any age. There is nothing to add to the booking, no form, no escort, no gate handover and no named-adult collection at the far end.
The phrase that matters is same reservation. It is not enough for an adult to be on the same flight on a separate booking β the child and the adult need to be on one record. If you booked separately, that is worth fixing before the travel date rather than explaining at the desk.
Who counts as the accompanying adult
This is the part the published rule does not spell out, and the part most worth checking for your specific booking.
The commonly reported threshold is that the accompanying traveller must themselves be at least 15. That matters in two real situations:
- Siblings travelling together. A 16-year-old flying with a 10-year-old is a different proposition from two 13-year-olds, and only one of those is likely to be accepted.
- A teenager escorting a younger child on a family trip where the parents fly separately.
Because the airline's own wording does not define the age, confirm it for your booking before you buy two tickets on an assumption. This is a five-minute question with a definite answer and an expensive outcome if you get it wrong.
Ignore the fee figures you will find online
A good deal of what is published about this airline and children flying alone is simply out of date. Pages still describe a programme for ages 5 to 14 with a charge each way, which is how the policy looked before it was withdrawn in 2018.
Those pages rank well and read confidently. They are describing something that no longer exists. If a page quotes you an amount for this airline's unaccompanied minor service, that is a reliable sign the page has not been checked in years β and a reason to be careful with everything else on it.
