Daylight savings throws airline schedules all out of whack

November 6, 2007 by Evan Sparks

The Cranky Flier draws attention to a little-noticed aspect of this past weekend’s end of daylight savings time: its effects on airline schedules. Normally airlines deal with these sorts of things by making necessary adjustments (especially complicated, he says, for flights between the northern and southern hemisphere, where daylight savings is going on when it’s not for us.). But Congress’s extension of DST for two weeks in October is really throwing a monkey wrench into transatlantic scheduling:

[A]t congested airports like London/Heathrow or Frankfurt, the airlines don’t have slot flexibility so I assumed they’d have to just change around their flights in the US. But what about when that involves flights at New York/JFK or Chicago/O’Hare, also congested airports? This gets very tricky and the result is a hodgepodge of schedule changes for some airlines. . . .

Look at JFK, however, and the London flights change both their US departure and arrival times. As you can imagine, arriving into the US an hour later means missed connections and longer waits for the next flight.

Aviation policy turns up where you least expect it
