Breeze Airways, the startup launched by JetBlue founder David Neeleman, announced a major expansion, including the first destinations in the western US and the first cross-country flights. The carrier, which started flying last May, said it was adding flights in 10 new cities, including Las Vegas, Los Angeles, San Francisco, Nashville and Jacksonville, and boosting service in others, including Charleston, South Carolina, and Hartford, Connecticut. Of the 35 new routes, just three have nonstop service on other airlines, including Nashville-Hartford, which is served by Southwest Airlines. Breeze will offer flights only a few days a week on most of the routes instead of daily service. All the West Coast routes will be served by A220 aircraft. Shorter routes are served by Embraer E-190 and E-195 planes. The carrier expects to take delivery of one new A220 a month for the next six years. The first new aircraft have 126 seats, including 36 “Nicest” first-class seats, 10 extra-legroom “Nicer” seats and 80 standard economy seats. Later deliveries, the carrier has said, will be configured with 137 seats, consisting of 12 first-class recliners, 45 extra-legroom seats and 80 standard economy seats.
