United Airlines continues its post-holiday blitz on last-minute airfares out of the Twin Cities. This week United is offering more than a dozen U.S. cities on sale. Roundtrip fares out of MSP drop as low as $88 (Chicago, next weekend) to $228 (to San Luis Obispo).

For the past several months especially, United has been consistently offering some of the best last-minute fares out of the Twin Cities. Granted, the destinations aren't always the marquis locations -- Allentown for $178, anyone? -- but they offer us flatlanders a chance to hit quite a few off-the-radar locations.

Not to mention Canada. The sale also includes several Canada destinations, including Halifax ($508) and Victoria, BC ($508).

The usual terms and conditions apply (purchase by Friday; depart Saturday, return the following Monday-Tuesday, etc.).

And U.S. Airways is offering an international fare this week to Amsterdam, Netherlands, for $770. And you know what they say about Amsterdam these days: Whatever you do, just don't joke about your underwear.
