US airlines have recently expanded their controversial peak travel day fees on domestic tickets to include the most popular vacation dates across the entire calendar year.

In late September, American Airlines broke with tradition and became the first airline to explicitly charge a $10 (€7) premium each way for three days around Thanksgiving and New Year's Day.

As expected, nearly every major US airlines has followed suit, but now the fees are being applied to nearly ever major travel holiday, according to the website FareCompare on October 9.  

Only US budget leaders Southwest and JetBlue have not added the surcharge and have stated they do not plan to follow suit.

The levy follows the introduction of various other new charges for checked luggage, seat choice, food and other services that were once included in the ticket price.

The good news is ticket prices for winter holiday fares are currently running 12 to 15 percent lower than last year due to lower oil prices and reduced demand, according to the website FareCompare.
