This is all good advice. So much of comfort is temperature, and so layers are key. Nothing is worse than spending 8 hours being *just* cold or hot enough to be uncomfortable.

my only amendment to this would be window seat for red eyes or early flights less than an 3 hours so I can sleep - i can hold my bathroom issues [usually] for a 1-2hr flight and i rather be able to lean against the wall for some Z’s
