Overzeetop , for travel to, from, or within the United States, you are entitled to a full refund if your flight is cancelled -- regardless of the reason or where you bought your ticket, even on Basic Economy tickets:

("Cancelled Flight – A consumer is entitled to a refund if the airline cancelled a flight, regardless of the reason, and the consumer chooses not to travel.")

In addition, passengers with elite status in an airline's FFP or its associated global alliance might enjoy certain elite benefits even when flying on a Basic Economy ticket. AA, for example, still allows BE passengers with elite status to use priority check-in lines, check one or more pieces of baggage for free, select a Main Cabin Extra (extra-leg-room) seat for free, and board earlier than non-elite passengers.
