With a doctor’s note, American Airlines, LAN Airlines and TAM Airlines will allow a pregnant passenger to re-book without fees or request a full refund, according to the airline.
Southwest Airlines said it will continue to follow the established CDC guidelines, and as always, customers can change their travel itineraries without a change fee.

Carnival and its sister companies will let pregnant women and their spouses either switch to a route that doesn’t include a CDC alerted area, or hold a credit and re-book for a later date.
