Frontier Airlines just launched a sale with fares from more than 20 cities starting at just $19 one way ($38 roundtrip, including tax). This sale ends tonight at midnight ET, so book ASAP.

Members of Frontier’s Discount Den can save even more, with fares starting at $15 one way ($30 roundtrip, including tax). However Frontier has recently started charging $49.99 per year for this membership. If you book two tickets for $15 one way as a member, instead of $29 as a non-member, then the membership fee is already worthwhile for you.
