Business class actually makes sense financially. It's very close to the same cost as a coach ticket and you get the aforementioned perks. Also, you get to skip the long lines in all the airports as both bus/first are separate there too.
I guess if you really want to fly on the cheap, southwest is ideal. If you're going to be checking a couple bags, and carrying on two more... having that snack and soda on the flight, etc.. I bet it's not all that much cheaper than a ticket on American.
Ok, like first off, I play the credit card points game and I get the A List SW frequent flyer, so I get to skip all those lines too. I used the flyby lane in security which is usually shorter than precheck. That means I have to take my laptop out, but keep my shoes on and use the metal detector instead of the MRI.
And on Southwest : Two bags free, snacks free and they send me drink coupons for free drinks to get me started. NO EXTRA COST.
Now you if you think business class and cattle class are close in price on those expensive airlines, te salud, Don Corleone...
