I hope they’re not permanent! My last trip was book-ended with two overnight flights and I still have not recovered. The fact that I was on the ground only 48 hours didn’t help. Couple that with the fact that I rarely obey all the things one is supposed to do to avoid this lagging. Perhaps that’s why the only one who feels sorry for me is me!!
You know you did a quick turn around when the same flight crew accompanies you both ways!
