I can't see SWA going to other countries for at least 5-10 years as there are not enough unilateral agreements in place and the open skys program won't be open for quite awile. Right now SWA can't fly into Canada and pickup Paxs and fly back to the states. This is known as cabatoge. Yes, Hamilton would be a better choice but if YYZ gets it rent reduction from the government, the prices of the fares should reduce. There are many other taxes that should reudce like the security fee and the NavCan fees. I have booked through US Airways a couple times from YYZ for $320 CDN which was almost the same prices as BUF with exchange and parking, I saved the drive.
