Going on a long flight (Tips please)

I travel a lot. I really tend to retain water and for me, I swear by compression leggings (mine are lululemon) for flights over 4-5 hours. Last week, I traveled from eastern Canada to Singapore and back, and also added compression socks - I was pretty good after the 13.5 hour plus 6 hour plus another 1 hour series of flights. Drink as much water as possible (get an aisle seat for easy access to the bathroom!), and as everyone else said, keep moving during the flight and between them, be mindful of sodium intake a day or two pretravel, etc. I’m a big believer in exercise as soon as possible after getting to your destination, and get outdoors to help adapt to the time difference, if that’s an issue. But the compression tights and drinking lots of water are my top tips. (I always have wine and eat the food because what else am I going to do up there??? 😂)
