the final Frontier

In this case the rules are intentionally predatory. How many people show up to the gate (not the airport) expecting to have to cough up 100 dollars AS THEY BOARD just because their backpack doesn't quite fit into this company-specific sizer. Even straps hanging out of of the little space are causing people to have to pay, according several reviews I have read. The rationale is that they need the backpacks to fit under the seats but this 14 by 18 by 8 inch "gotcha" tactic is way smaller than what fits under the seat comfortably, and what they are traditionally used to--a one hundred dollar difference between "carry-on" and "personal item" is a shock to most travelers. I've never heard of such a thing in my years travelling until reading reviews online for Frontier. I agree that budget airlines are more likely to surprise you with a fee but this sounds bonkers. Glad to see the courts are addressing this specific issue I mention.
