Valentine’s Day: Sweet savings with JetBlue, Frontier flash sales

It’s just what I wanted for Valentine’s Day! A one-day sale from JetBlue Airways and Frontier Airlines with really cheap spring airfares to Northern California, the East Coast and other destinations.

JetBlue Airways: The Love-A-Fare sale offers one-way airfare to New York’s JFK Airport for $145 from Long Beach, Los Angeles and Burbank. Other one-way fares from Long Beach include $39 to Las Vegas; $50 to Sacramento, San Francisco and Oakland; $80 to Salt Lake City and Seattle; and $90 to Portland.

The fine print: The offer is good until 8:59 p.m. PST tonight (Tuesday) for travel between Feb. 21 and April 3 with some restricted travel and blackout dates. I checked online this morning (Tuesday) and found good availability for $80 tickets each way from Long Beach to Seattle on Feb. 23 to 27. Contact: JetBlue, (800) 538-2583

Frontier Airlines: The Valentine’s Day Sale offers one-way fares from Los Angeles for $71 to Denver and $141 to Aspen, Colo.

The fine print: This offer also is good until 8:59 p.m. PST tonight (Tuesday) for travel through March 8 with a three-day advance purchase. Again, dates of travel are restricted. I didn’t find wide availability, but this deal could work for those with flexible dates. For example, I found availability for the $141 airfare from L.A. to Aspen good for a trip from Sunday to Feb. 21 and from March 5 or 6 to March 9 (even though that return date falls outside the travel window). Contact: Frontier Airlines, (800) 432-1359.
