JetBlue's Big Winter Sale has returned. The New York-based boutique airline is once again offering one-way tickets for as little as $44. The sale lasts two days and ends on Wednesday night.

JetBlue offered the same sale from January 3 to January 4.

The best deals are concentrated near its bases in Boston, Massachusetts; Fort Lauderdale, Florida; and Long Beach, California.

Standout deals include a round trip between Long Beach and San Jose or San Francisco - as well as flights between Atlanta and Orlando - for $88. A round trip between Long Beach and Las Vegas can be had for $104.

Flights between Boston and Pittsburgh or Rochester, New York, are available for $98 round-trip. One-way flights from Boston to Minneapolis or Orlando are just $64 and $79, respectively.

There are also some great deals on flights between the Northeast and the West Coast of the United States.

Flights between Boston and Seattle or Burbank, California, can be had for $228 round-trip. The same price applies to round trips between New York and Long Beach or Ontario, California.

There are instances where we were able to find flights for less than the posted sale fare. For example, we found a round trip between Long Beach and San Francisco for just $85, $3 less than the sale price.

Naturally, there is some fine print associated with the sale.

All sale fares must be booked by Wednesday at 11:59 p.m. ET or your local time zone, whichever is earlier. Tickets must be for travel between January 16 and April 10 - mostly on Tuesdays and Wednesdays - excluding February 19 and 20.

The sale prices are for the airline's "Blue" fare, which allows for a free carry-on bag and a personal item. A checked bag will cost an additional $30.

According to JetBlue, all posted prices already include government taxes and fees.
