I would love planes to improve on their timing and turbulence, rather than simply add more gadgets and things to buy. However polish seems to be the way it goes in the flight business and the latest improvements are even expanding out of the planes and into airport lounges.
In some new and existing terminals around the world, evolution in the pre-boarding experience involves: better seating, made-to-order meals, valet parking, car washing while you travel, art exhibitions, WIFI access, spa treatments and more.
What about the planes? Like doing something about their punctuality and bumpy rides?
