We know you’ve been waiting to take that family vacation to Mexico but just you can’t afford the airfare. Don’t cancel your plans just yet, because with Club Premier, children can fly for free. That’s right, from now until Dec. 31, for each adult ticket purchased from the United States to Mexico for selected, non-discounted fares, a child flies for free on the same route and itinerary. This offer does not apply for those flying from Las Vegas to Mexico City, but it is valid from most U.S. gateways except for JFK (New York) and MCO (Orlando). You have to be a Club Premier member to participate in this offer, and the promotion is only available on coach fare roundtrips, which means you have to sit in the cheap seats, but there’s no reason to complain when we’re talking about free travel. There are also some blackout periods to keep in mind, but remain calm, as there are only two you have to worry about. The promotion is not available Oct. 29 through Nov. 6 for travel to beach destinations. The offer is also blacked out Nov.19-27 for the Thanksgiving holiday.

Free travel only applies to children 12 years or younger who are enrolled in the Club Premier program. If your child is not currently a member of the Club Premier program, you can call Club Premier Customer Service at 1-800-247-3737 to have them enrolled. You can also fill out an application form, which can be found at Aeromexico ticket counters, or fill out an online enrollment form at www.aeromexico.com. The companion child must travel on the same flight and itinerary as the adult who purchases the qualifying ticket, and the companion ticket will not accrue Club Premier miles. This offer is only valid on three digit flights operated by Aeromexico and does not apply on four digit codeshare flights.
