British Airways is to introduce changes to the way air travellers select and book their seats from 5 December 2006. All seats not pre-assigned will be offered for selection and to assist air travellers in choosing a seat the airline has improved its aircraft seat maps on ba.com, which display up to the minute seat availability for each flight. The maps will now display emergency exit seats and highlight the position of the toilets, infant cots and the crew galley areas.
