Is Christmas day air flights busy?

In most airports, it is actually less busy because most people travel before of after Christmas because they want to be with their family. Though if you are not like that, travelling on Christmas day is perfect.I'd like to know answer to this too - i have changed my flight from boxing day to Christmas Day next year and saved money - is this because it is not popular to fly on Christmas da?

Are we talking about Christmas day according to the western tradition? Or are we talking about Christmas day according to the eastern orthodox traditions? I bring that up because of the last Word in the previous paragraph? "Da" indicates the respondent was perhaps of Russian decent which would indicate that Christmas is determined according to the eastern orthodox tradition, which would be January 7th.
