If I were on a flight and anybody started singing, I would be pissed…..harder to sleep or work or listen to what I want to listen too. I love Jesus as much as the next person, but one should be able to see this is clearly inappropriate and the flight attendants should have put a stop to it.
Guitars and airplanes don't mix well.
I love God but I would hate for people to break out singing any song in an enclosed space. It’s not polite. However if the intention was to cheese off Omar, I would join in.
