The tickets can be purchased for travel from May 15, 2025, and August 18, 2025. Travelers should be aware there are several blackout dates, and the tickets do not include perks such as seat assignment, carry-on luggage, or checked baggage, all of which require extra fee payments.

The flights will begin service on a gradual, rolling basis between May 15, 2025 and May 24, 2025. The airline shared with T+L they expect these to be full-year routes, with some seasonal adjustments as needed. The May takeoff makes them perfect for travelers looking to book a summer vacation, or early fall trip.
