After talking to somebody else who flew out of Tijuana last month, I guess the proper way when crossing by foot is to tell the agents at the border that we have tickets to fly out. Supposedly they will wave us through and tell us that we will be required to get our FMM at the airport, as without it we will not be allowed to board. I also learned that it is important to save the FMM stub as we will need it to board our return flights back to Tijuana.
