Okay, well while we are on the subject of headwinds/tailwinds, I too have noticed the longer flights. We had headwinds of 140 miles per hour going to SEAlast week which delayed us about 20 minutes.. this was just LAX-SEA.
A story I have regarding headwinds/tailwinds: I remember flying to NRT in January a couple years ago from LAX. It took 11 hours. Coming back, the tailwinds were between 190-200 mph and it took only 8-1/2 hours. Our airspeed read on the air show as much as 740 mph which was incredible. One man next to me said he had never flown that fast. The pilot said it was the fastest trip he had taken that year.
