if the government wants to increase taxes in this "new" model..they can, and noone will notice.
from the Spirit site...
"If the government can hide taxes in your airfares, then they can carry out their hidden agenda and quietly increase their taxes. (Yes, such talks are already underway.)"
And you just stated, consumers won't notice...and even if they do notice the price to visit grandma next year went up 10 bucks, they will blame the airline...not the government.
The low cost airlines, like Spirit, Frontier, Southwest, etc...don't price like the big boys (yield mgt faring, leading to 100 different prices on one flight)...usually its last minute, 7 day, 14 day and "wanna get away" specials...thats why the big complaint comes from Ben at Spirit. No longer can they say Fares from $29..which was their fare...that came to 50 or so each way post taxes and security and pfc charges and all the other stuff uncle sam has loaded them down with.
