A few weeks ago, United's Danish website was way under-pricing First Class tickets from London to the United States, about $100 to anywhere you wanted to go. United said it would not honor those tickets, and I sided with United while noting that United States Department of Transportation (DoT) rules seemed clear that United couldn't unilaterally cancel its tickets.

Now the DoT has weighed in with a statement.

The statement makes clear that United will not have to honor the mistake fares.

Frontier Airlines is having a one day sale today with fares from $19 to $49 from Atlanta, Georgia to:

Austin
Chicago-O’Hare
Cincinnati
Cleveland
Denver
Indianapolis
Las Vegas
Los Angeles
Miami
Minneapolis/St. Paul
New Orleans
New York-La Guardia
Orlando
Philadelphia
Trenton/Princeton
Washington-Dulles

Tickets must be purchased by 11:59 PM ET today (February 24) for nonstop travel on:

April 30, 2015
May 5, 6, 12, 13, 19, 20, 27, 2015

These are all Wednesdays and Thursdays.

These promotional fares sell out really quickly.

Through 11:59 PM tomorrow February 25, 2015, British Airways is offering a 50% bonus on the purchase of Avios. This is the biggest bonus ever offered on the purchase of Avios.

The maximum Avios you can purchase in a year is 35,000. With a 50% bonus, that means you can add 52,500 Avios to your account.

I'm intrigued by flights and awards that don't involve America. If there's a cool award to get from Australia to SE Asia, that can be integral to a longer, better, and cheaper trip.

My two favorite continents to explore are South America and Europe.

I've wanted to fly Swiss Business Class for a while. It just looks really nice. The 6'6" beds nearly all have direct aisle access, and the food and lounges look nice.

Swiss flies to Zurich from eight North American cities and from Zurich throughout the rest of Europe.

Update: This fantastic deal ends in five days on February 28!

Avianca recently began flying the 787 Dreamliner from Colombia to destinations in South America and North America. Soon it will also fly the Dreamliner to Europe!

This is exciting because Avianca's fully flat Business Class looks very nice, award prices on the long intra-South American flights are super cheap, and this is be the most comfortable way to fly between the United States and Colombia.

I just flew Avianca's angled flat bed on its A330 from Bogota to Buenos Aires.

Yesterday I wrote about a discovery that shocked me: American Airlines is releasing consistent MileSAAver award space on its flagship and newest plane--the 777-300ER--in Business Class and First Class between Los Angeles and London.
