With all the add-on fees airlines are charging, watch out for more innovative ways to separate you from your money.
Here's an example of what they may come up with:
On-time Compliance Fee?
$100 per passenger
Hit your head on the overhead bin?
$20 per strike
Looking up at the bin you just hit? Another $5 (after all, you know it's up there!)
Roll-away steps?
$20 per person
(this is in lieu of the rope ladder at no extra charge)
