Common Allegiant Air support topics
Baggage claim. If your luggage arrives damaged, missing, or delayed, report it at the airport baggage desk before leaving and keep your baggage tag — the reference number is required for the online tracer. Compensation for lost baggage is governed by the Montreal Convention.
Refunds and reimbursement. Refund eligibility depends on the fare rules of your ticket. Non-refundable tickets may still qualify for a tax refund or travel voucher. When Allegiant Air cancels a flight, you can request a full cash refund via the online form regardless of fare class.
Name change and booking modification. Minor spelling corrections (up to 3 characters) are typically free. Larger changes, passenger substitution, or date/route changes follow your fare's change rules — check "Manage my booking" before calling.
Online check-in. Allegiant Air online check-in typically opens 24–30 hours before departure. At Harry Reid International Airport and most major hubs, you can drop bags at self-service kiosks. Mobile boarding passes are supported in the airline app.
Special assistance. Request mobility, medical or unaccompanied-minor assistance at least 48 hours before departure through the contact channels above. Bringing a service dog or medical equipment requires advance notification.
