If you can choose the seat next to the window in row 12. There's no seat in front of there so you have so much room!

Don't ask the flight attendant to move the food trolley so you can vomit in the toilet, they get cranky and tell you to use the spew bag
Oh! Thank the lord that the food trolley wasn't out when Mr Chunder on my flight needed to! Totally reeked of big night out on the town - Yuuukkk!!
