Gabriel,
A mi no me importa tanto que parezco joven-- ya con 24 anos, trato de mantener la juventud lo mas posible.
Lacsa does fly from YYZ-- the flight goes YYZ-HAV-SJO. I wonder for U.S. citizens booked YYZ/SJO with an intermediate stop, would this count as a semi-legal way for us to transit Cuba? Anyway.....
Different airlines seem to have different preferences with partners, i.e. TACA may want to send you YOW-MIA on AA and connect to TA, but with LatinPass itself you must use TW and US to connect to the gateway. Also, it happens that the international airlines can't hold space on the U.S. carrier for more than a day. So, what we did is reserve the flights with TACA and hold them for a week, then the day we wanted to ticket, we called TACA and requested they force in segments on TW-- that started the 24 hour clock for ticketing. We then called LatinPass that day with the confirmation code, and they took care of ticketing.
The way the LatinPass office is set up, they are at 1600 LeJeune Rd. on 2nd floor; TACA has an office on the 1st floor, and COPA also has a ticket office in the building. So I don't know if a LatinPass rep physically goes to a TACA/COPA agent to ticket it there, but they did ticket it and send it out.
If you happen to move miles to Distancia and ticket with them, you can use AA flights to connect to TACA. I don't think there's a way to use CO flights to hook up with COPA, though, since you can't actually move LP miles into Onepass, and you must always ticket COPA through LatinPass.
