If you're one of those who has forgotten their passport on a quick dash to the airport - you're pretty much on your own. A survey by Dublin Bus has found that 97% of people say they have never left it behind them.
The results of a poll to mark the expansion of the company's Airlink route has also found over half of Irish people pack for a holiday the day before they go away.
The 747 route, which has run on the North-side for years, is now bringing South-side passengers to and from Dublin Airport with the introduction of the 757 route.
According to the survey of over 1000 people, most Dubliners like to get to the airport 2 hours before their flight, and when they get there the thing that annoys them most is people at security not being prepared.
Almost eight in ten people bring presents home from a holiday, but 4% admit they buy them when back in Dublin and try to flog it as foreign.
