The DOT’s refund rules have been significantly strengthened in recent years. Airlines operating in the US must now provide automatic cash refunds (not vouchers) when flights are cancelled or significantly changed, checked bags are significantly delayed, or paid ancillary services aren’t provided.
A "significant change" is defined as: a departure or arrival time change of 3+ hours for domestic flights or 6+ hours for international flights, a change in departure or arrival airport, an increase in connections, or a downgrade to a lower class of service. The refund must be issued within 7 business days for credit card purchases.
For business class travellers, the DOT refund rule provides important protection on high-value tickets. If your business class booking is significantly changed or downgraded, you’re entitled to a full cash refund. BookMyBusinessClass advocates for clients’ refund rights and assists with DOT refund claims when flights are disrupted.

An award chart that prices redemptions on great-circle miles flown rather than region pairs, typically with peak / off-peak tier modifiers. Aeroplan and British Airways Avios are the two most prominent distance-based charts among major programmes; they are predictable and reward shorter stage lengths disproportionately.
Dynamic pricing is a pricing strategy where airline ticket prices change in real-time based on demand, supply, booking patterns, and other market factors, meaning the same seat can have vastly different prices at different times.
A direct flight operates from origin to destination under a single flight number, though it may make intermediate stops. It differs from a non-stop flight (no stops) and a connecting flight (different flight numbers).
An e-ticket (electronic ticket) is a digital airline ticket stored in the airline’s reservation system, replacing the traditional paper ticket. It is identified by a 13-digit ticket number and linked to your PNR.
Direct aisle access means every seat in a business or first class cabin can reach the aisle without stepping over or disturbing another passenger, typically achieved through 1-2-1 or 1-1-1 configurations.
Economy plus (also called extra legroom economy) is an enhanced economy seat offering additional legroom and sometimes priority boarding, without the full premium economy cabin experience.
