Are inflatable travel pillows actually comfortable enough for long flights?

The consensus across r/onebag, r/TravelHacks and verified-purchase reviewers is mixed but trending positive: inflatable pillows are noticeably less plush than memory foam, but they pack to a fraction of the size, and the better designs (H-shape, contoured, or hybrid foam-and-air) get close enough on comfort that most travelers accept the trade. Reviewers who hated inflatables typically tried thin, round U-shapes that didn't sit high enough to support the head.
