Mainline carriers from George Bush Intercontinental Airport (IAH) — including American Airlines, United Airlines, and JetBlue — provide reliable service to Caribbean hubs such as Miami (MIA), San Juan (SJU), and New York/Florida gateways, where passengers transfer to regional carriers bound for Anguilla (AXA). American often offers strong connectivity via Miami and Charlotte, United provides solid hub links via Newark/Washington, and JetBlue is competitive on SJU/SXM routes. For the final island leg, regional airlines (e.g., interCaribbean, Winair) or ferry services operate between St. Maarten/Antigua and Anguilla; service levels, baggage allowances, and schedules vary—confirm policies and consider booking combined or protected itineraries to reduce disruption risk in December.
