how do you keep yourselves warm on a flight?

Hi all! I'm going on a trip to Thailand next month, and although ilang beses na akong nakasakay ng eroplano, di ko parin alam how to keep myself warm sa plane 🥲 lamigin kasi talaga ako huhu

To give you guys an idea kung ano yung usual na sinusuot ko sa airport:

• shirt • jacket • long pants • thick socks • closed shoes

bonus: may bitbit pa akong blanket & face mask (para somehow maka-help yung breath ko na painitin face ko)

Kahit na ganyan na sinusuot ko & binibitbit sa flight, nilalamig parin talaga ako 😭 sinasara ko rin yung vent sa ulohan ko pagka-upo. I also order hot drinks to keep me "warm", pero temporary lang talaga lahat 🥲

Please drop all your suggestions below 😭 pagod na talaga akong lamigin lol if may mga product recos din po kayo, please share links!

Thanks in advance!!!
