Canada to San Salvador Direct Flight
I was looking up some info on the TACA web site and noticed they offer a direct flight from Toronto to San Salvador. As the typical TACA flight from the US to Nicaragua stops in San Salvador, that looks like a good option for Canadians who wish to avoid a US stop.
Note that I was talking to guy from Germany yesterday who has done a lot of traveling. He told me that Brazil has installed US-style airport scanners but they only use them for people traveling on US passports. He was amused.
