Not that long ago, major airlines added a $10 surcharge if you were flying near the holidays.

According to this story from Associated Press' David Koenig, it just got more expensive. He writes:

"Several of the largest U.S. airlines have increased a surcharge for travel on the busiest travel days to $20 each way, up from $10. The surcharges apply to a large number of flights within the U.S. on more than a dozen peak days around holidays including Thanksgiving, Christmas and New Year’s. Delta, American, United, US Airways and Northwest all boosted their surcharge on some routes, said Tom Parsons, who runs the discount travel site Bestfares.com."

Buy those tickets quickly before airlines raise the fee again. Or, maybe this is the year to call home for the holidays.
