These are the type of bags that should be used in the aviation industry. Extra wide opening to go over your mouth, plenty of capacity and they will not leak. Unfortunately, at least currently there is no way of storing them conveniently behind every seat of an aircraft. They do have dispensers, used by the medical profession but they take up too much space if you had them installed.

The current air sickness bags are worthless. When used, majority of what is thrown up finds itself outside of the bag than inside of it due to the velocity & volume what a human body can create when sick.

Never understood why more passengers don't have their air sickness bag ready if they start feeling sick. On one recent flight, during final approach, I had one passenger who was sitting in the window seat turn towards me and decides to throw up in the direction of the empty middle seat. I got splattered, hit the call button but the FA refused to get up and hand me a towel. I yelled back and had them toss me a towel. It stunk and was disgusting. I wasn't upset about the passenger getting sick, but I was upset that he failed to utilize the air sickness bag and felt it was important to throw up on me, rather than himself.

Vomit is a bio hazard, I'm surprised the airline didn't have anything better to give me than a towel. I sure felt sorry for the passengers who had to sit in that row on the next flight. The good news, I was home.
