This should do
During a flight, many of us like to get comfortable, tune out the noisy environment (especially when babies are on board), close our eyes, and not open them until we reach our destination.

This guy made sure he had absolutely no distractions. He didn’t want to see, hear, or smell anything during the flight. In times like these, you can’t be too safe, and it wouldn’t be surprising if more passengers adopt this look for future flights.
