I plan to go to Mexico in about 1-2 months. I'll have to get Mexican electronic authorization (SAE).
There're cheap tickets 2 months from now.
SAE should be submitted, however, not earlier than a month before one's visit to Mexico -- this is a rule.
If one buys a ticket a few months in advance because they're cheap and a month before his flight he submits SAE and gets rejected -- this will be troublesome.
My question: is it strict that SAE should be submitted a month before one's trip to Mexico and not earlier than that?
How can I get away with buying tickets that are 2 months from now?
