I always find Bag, Airsickness Nato stock no 8105-99-130-2180 pretty good.
Self sealing and thick and big enough for a really big barf.
Also when flying with inexperinced SLF, l take a wrap of paper towels and some wet wipes. (bum wipes are even bigger)
Also carry a 40D 8465991376876 Bag Crew Relief but never had to use it yet. (came close once mind,but that's another story
