From Airbus, the folks who floated the standing up flights trial balloon, this:
“Thankfully” nothing – When the seats are so narrow that the little head pillows are shown narrow side up, you know it’s hell.
Those seats are not wide enough for the average adult, but the 3rd graders may do OK.
Pity the fool who gets the aisle seat, too. Those are narrow aisles.
As for BUDGET economy, a friend just told me that the EU countries are charging a US$500 travel tax on flights from the US. How’s that for “BUDGET economy”?
