People can get really creative in order to find a comfortable position. As long as you don’t bother your fellow passengers, we are all up for it. But please do not take your shoes off.
If you hate summer and hot temperatures, we feel you. We are right there with you. But please, for the love of God, keep your clothes on. No one wants to know what color bra you’re wearing today. No matter how hot it is in that plane, you can’t do that.
