A sickness bag (also known as a sick sack, airsick bag, airsickness bag, emesis bag, sick bag, barf bag, vomit bag or motion sickness bag) is a small bag commonly provided to passengers on board airplanes and boats to collect and contain vomit in the event of motion sickness. Hovercraft-ferry operators and even train companies have also been known to furnish bags. Pregnant women with morning sickness and travelers who know they are prone to motion sickness will sometimes bring their own bags.
The plastic-lined airsickness bag was created by inventor Gilmore Schjeldahl for Northwest Orient Airlines in 1949. Previously bags had been made from waxed paper or card. Modern bags are still mainly made from plastic-lined paper, but a significant proportion are now made completely from plastic.
Among the collectors of aeronautical memorabilia there is a sub-culture of sickness-bag aficionados. The Guinness Book of Records recognizes Dutchman Niek Vermeulen as the world record holder for the number of different bags (6016 as of 29 January 2010).
In 2004, Virgin Atlantic issued a limited edition set of half a million bags in collaboration with designer Oz Dean of 'forcefeed:swede'. Oz had conceived and run an online gallery of sick bags since 2000 under the project name "Design for Chunks". It challenged designers to illustrate the usually dull medium of the sick bag, as opposed to T-shirts or splash pages which were the standard challenges at the time.
Although the project achieved cult status in a short time amongst the design community, Dean felt that it had run its course and closed it down in 2003. With the offer of doing the project for real (from Virgin Atlantic) "DFC" was opened up again, in 2004, with the strapline "This time it's real!" The printed bags were intended to be on the global fleet of planes for 6 months but only lasted 3, with people walking through the aisles collecting the sets. The project divided opinion and this came as no surprise to Virgin Atlantic which is intentionally the more offbeat airline company in comparison to their traditional rivals, British Airways. The whole set of 20 finalists designs as a framed piece can be found in the Virgin Atlantic Clubhouse at Heathrow, UK or online at the archived website.
