I saw on the news here in Syracuse that JetBlue is starting service here to NYC in May. Apparently they're hoping that JetBlue's presence will convince AirTran or Southwest to start service here as well.
YYZ-FLL has got to be one of the cheapest routes to US from Canada. I just saw one on expedia.ca for $217 WITH TAX. Tickets to Miami can be seen for as low as $119 without tax. I quite content with the level of competition to sun destinations from YYZ.
As for JetBlue serving YYZ or other destinations in Canada- like it was stated earlier, it won't happen for a long time. Even if they were allowed to serve Canadian destinations, I doubt they would want to absorb high costs of flying across the border. BTW, many Toronto residents drive to BUF to take advantage of cheaper fares- as I have done numerous times in the past.
Okay... now that we've established SYR to be the next city, you've got to remember that they're planning on starting service to another 9 destinations this year and then another 10/year for the next two years after that.
If they don't get to your city this year, they're probably planning on starting service there sometime soon. JetBlue seems to be focusing on cities with extremely high airfare and some of these are hubs or focus cities.
With that in mind, I have a really good feeling that they're going to hit PIT or PHL sometime soon. I think that PIT has a better chance over PHL.
I hope that Jetblue will fly to SJU out of JFK. My hispanic friends are sick and tired of AA's high fares out of JFK as well as they long drive to EWR out of Queens for a better fare on CO. Since TWA will bite the dust soon I hope JB will pick up where TWA will leave off on the JFK-SJU route. Puerto Rico is a US commonwealth and Puerto Ricans have US passports so I'm sure even they can fly to SJU on their current flight certificate.
