Green Card holders now need to show 'Real ID' to fly within US

All Green Card holders in US will have to show a 'Real ID' for domestic air travel from May 7. A 'Real ID' is a driver's licence/state ID with a star/flag/word "Enhanced" on it, according to US' Department of Homeland Security (DHS). If the passengers don't have a compliant driver's licence/state-issued identification, they will have to carry a valid passport.
