Brief Summary
Hereditary Haemorrhagic Telangiectasia (HHT) is a condition in which sufferers have abnormal blood vessels which makes them more likely to bleed than other people, particularly in the lungs, which results in low blood oxygen levels. Flying may make this worse and cause problems. The investigators want to know if there are an increased number of problems on flights compared to on land. The investigators currently do not have any evidence based guidelines on air travel to best advice people who suffer with HHT. The investigators would therefore like to ask individuals who have HHT about their experience on a flight, using a postal questionnaire.
