There are some claims (common but contested) that the lower air pressure (and humidity) in a plane’s cabin increases the risk of thrombosis.
Another factor is that buses usually have toilet breaks every couple of hours, which gives everyone an opportunity to stretch their legs – and people are more likely to make use of these opportunities than to do it regularly in a plane because there is more room and they’re reminded and encouraged by the bus stopping and lots of others getting off.
