I know there are already some posts about this, but no one seems to have the right answer, so I wanted to ask again maybe there are better products or solutions by now.
Next month, I have a 15-hour flight from Croatia to Seoul, and I want to try to sleep most of the way, maybe 8-10 hours. The biggest problem is obviously my head. Without support, you get a stiff neck and your head keeps falling forward.
Some people say the TRTL pillow works well, but it costs $70. Other travel pillows are either not supportive enough or get too hot/feel too tight. I also saw a sleep mask that attaches to the seat behind to hold your head, but it seems like most European airplane seats don’t allow that or it might even be forbidden.
I’m 6’1” and prefer an aisle seat for more legroom. I hate window seats, so leaning against the wall is definitely not an option.
