  • To print a ticket: All passengers must enter the Aeromexico’s reservation code or e-ticket number (beginning with 139) and the passenger’s name exactly as it appears on the reservation.
  • Note: This procedure doesn’t apply to children 2 and under, as they do not require tickets to travel with FWG.




  • A printed FGW ticket is required to board the train. Travelers will find the date, time, route and train number printed on their ticket. Free seat the day of departure.
  • FGW does not employ ticketing agents to assist with this procedure and travelers will not be permitted to board trains with an Aeromexico ticket.
  • FGW tickets are valid on any departure. The passenger should always check departure screens at Stations for the exact departure times and check platform numbers since they can be altered at short notice.
