Compression socks on overnight international flight

Best Practices for Compression Socks on an Overnight International Flight

We’re heading out tomorrow for our first European trip, and we’ve been fortunate to snag Business Class seats for an overnight journey. In preparation, I picked up compression socks after hearing recommendations from Reddit and after recently dealing with ankle swelling following a 14-hour road trip.

Question: During the overnight portion of the flight, when I’ll be able to rest and sleep, should I keep the compression socks on or switch to regular socks? I’m unsure whether sustained compression is safe when I’m lying down and not actively moving around.

If you have experience or guidance, I’d appreciate your advice.
