Thanks for the reply !
after numerous calls to Aeromexico--


<<8. This ticket is good for carriage for one year from date of issue, except at otherwise provided in this ticket, in carrier’s tariffs, conditions of carriage, or related regulations. The fare for carriage hereunder is subject to change prior to commencement of carriage. Carrier may refuse transportation if the applicable fare has not been paid.>>

so i can only book the same ticket again, plus the fees.

$150 penalty.
