I have a longish flight for the first time, 5 hours. I have a couple dumb questions about flight etiquette? 1. I have a window seat, when I get up to use the restroom I just ask the people next to me to let me out right? 2. If the bathroom is occupied, what do I do? Wait outside the door or walk of shame back to my seat? 3. Im really worried about DVT (partially because TikTok fear mongers and I am an anxious person) how do I prevent it without getting up too much? 4. Im pretty short and have troubles lifting things above my head, can I ask the flight attendants to help me put my carry on in the bin?
