In May 2025, Avelo Airlines added four new airports to its network: Chicago O’Hare, Grand Rapids, Long Island, and Portland, Maine. Notably, Avelo shifted operations from Midway to O’Hare, restoring HVN service after 29 years. With these additions, Avelo now serves 49 airports. Tweed New Haven remains its busiest hub, accounting for nearly a quarter of its total departures during the last week of May.
