The committee said that seating arrangements on flights paid no consideration to passenger comfort. The report called for small display cards at the ticket sale point which asked passengers whether they were fit to fly. In addition, it said, airlines should give health briefings as part of the pre-flight safety drill. However, it found that there was no evidence that airlines were compromising the quality of air in the cabin in order to save money. The precautions passengers can take to avoid DVT include drinking plenty of water and exercising during the flight.
Some airlines already suggest passengers exercise during long flights.
The Civil Aviation Authority already specifies minimum seat dimensions for aircraft manufacturers, but a spokesman said its remit was plane safety rather than passenger health. We might have an issue with health information being part of the pre-flight briefing, if it detracts from the safety aspect of the briefing. The committee will also call for better standards to reduce the risk to passengers and crew of infection from poor ventilation and air quality.
