US Airways has a $134+tax fare each way between Washington National airport and Fort Lauderdale. Decent enough fare during normal times, it prices out at about $309 roundtrip. But this is a first class fare. (And this morning it was pricing out about $50 less!)
West Palm Beach is available for $399 roundtrip all-in. Compare this to American’s discounted “KUP” fare, DC to Miami of about $900 roundtrip.
First class for the price of advance purchase coach, the fare won’t last long for sure. It’s an “A” fare which is discounted/restricted first class so it’s non-refundable and carries a $150 change fee. Fare basis is AA7UPN.
