Travelers with disabilities: extra significant change rules

Different connecting airports or missing accessibility features count as significant changes.

Significantly delayed or changed flight

Domestic: departure 3+ hours earlier or arrival 3+ hours later. International: 6+ hours. Also: different origin or destination airport, more connection points, downgrade to a lower class of service, and for an individual with a disability, different connecting airports or a substitute aircraft lacking a needed accessibility feature.

14 CFR 260.2 (Significantly delayed or changed flight)

When the refund is automatic

Refund is due when (i) the flight is cancelled and no alternative is offered, (ii) the consumer rejects the changed flight, rebooking, or compensation, or (iii) the consumer does not respond and the flight departs without them, or does not respond to a voucher offer by the original departure date.
