Your plane tickets to grandma's house for the holidays just got a bit more expensive. As if peak holiday fares aren't expensive enough, Delta, American, United, and US have added $10 per ticket on peak travel days. This will apply for most fares for travel on Nov 29th (Sunday after Thanksgiving), Jan 2nd and Jan 3rd. Most of you will be complaining of course, but the airlines are still cash strapped as mentioned in this blog post last week. There are ways to avoid the baggage fees, but no real way to avoid this surcharge unless you don't fly on peak days. As long as airlines continue to lose money, we'll see more tactics like this. The most likely new fee? Charging for advance seat assignments, a move already taken by several discount airlines and most recently by British Airways.
