JetBlue to reattempt Boston-Vancouver seasonally this summer. Air Canada recently trimmed the length of their seasonal service on the route.
American Airlines adding another frequency to Boston-Louisville.
Would have been interesting for American to try Boston-Greenville SC.
Not clear from press release when these changes come into play.
Didn't they also plan a longer run of 3 weeks for 2023? While they're adding seats with the 738 MAX, it's going to run for a shorter duration than they did in 2022. Comments in airliners.net indicated the route ran with high load factors, but that also doesn't provide a solid financial baseline for the route.
