Whoever invented the jetway was a genius. This piece of machinery conducts us from the airport terminal to the aircraft, out of the weather and along a generally sloping path that is much better than the old stairs. Here’s a look at a waiting jetway at Aruba’s Queen Beatrix Airport.

Lots of frequent flier miles begin and end in these jetways. And if you find yourself in a place where they don’t have one, well, then you’ve really gone somewhere else. Enjoy the journey.

Agreed about the usefulness of the jetways, but I have fond memories of my first few visits to Aruba — when you would deplane down the stairs and the warm Aruba breeze would hit you before you even entered the airport.
