Frontier Airlines sale ends July 27

Frontier Airlines is having a sale for travel Aug 21 to Nov 7, with lowest fares Tue/Wed/Sat for US/Canada travel and Mon-Thu for Mexico travel.

These fares are decent but not astounding, and other airlines have matched.

Examples:

• Memphis to Orlando $118 RT (Frontier, a Denver-based airline, flies the route nonstop, which surprised us)
• St. Louis to Phoenix $168 RT (but wait! Frontier has a lower fare for $159 RT travel any day of the week through Nov 14--just one of those quirky things)
• and Jacksonville/Denver for $199 RT, which every airline offers but only Frontier services nonstop.

This sale ends midnight MT on July 27.
