Get ready to pay a LOT more for airline flights.
You want "no middle seat", You want "two free bags" , you want "more space between rows"
You want "cheap airfare"
Umm...... the wants are not compatible.
There's ALWAYS been a way to have all you "wants". IT's called Business Class. Look at the price difference. If that's what you want then that may be what you have to pay. For a lot of us that will mean a lot less travel. If your round trip to Europe goes from $500 to $1500 what's that doing to your travel budget?
James's "law" is a joke. NO we aren't going to pass a law that says you get two free bags LOL! If they do dictate spacing then that might happen, but... see above.
Airlines have actually tried to succeed doing what we claim we want. Years ago American had a "more room in coach" campaign. They removed rows of seats, gave you more room and advertised it. Everyone said to them "oh yes, that's what we want". Then they got online and AA was $20 higher then Delta with "less room in coach". SO they booked Delta... AA gave up, put back the extra seats and lowered fares.
