I took a 10-hour flight, and one carry-on item made sitting in economy more comfortable

• I've long considered using a foot hammock to ease long-haul, economy flights. 
• I wasn't sure if it would be worth the space in my carry-on or if it would accommodate my taller height.
• I loved the accessory, which allowed me to bend my knees and get comfortable in the cramped seat.

I have a confession: I'm not always the most courteous person on a flight.

No, I don't pick...
