So they are further incentivising people who already shove everything they own into a "carry on" bag that barely makes it through the scanner, cant fit in the overhead, and probably weighs more then my checked bag? People already learned that if it can jam your bag through the TSA scanner then you can gate check your bag for free and avoid $25, $35, $100 etc charges. Now people not only will avoid the fee, but get to board early?
Instead of all these one off ideas just raise prices, bundle ALL services in it, and stop with this awful way of charging for items.
Also these airlines are not making huge profits off of the fees, if they got rid of them they would still have the same profits, but this way they can claim it differently for accounting purposes. I.E. it looks better on earnings reports & gives the appearance of a better return for investors/stock holders.
