Some passengers at George Best Belfast City Airport will be the first in the UK to take part in a major experiment which will allow them to book themselves on board - and through security - simply by using their mobile phones.
bmi are introducing the pilot scheme in four weeks time on their Belfast-Heathrow run. And if it proves a success, they will make it available on all their UK flights.
It is hoped that the new technology could substantially cut down on airport waiting times.
bmi sales manager Brenda Morgan said: "Belfast is ideal for the experiment and the trials are all ready to go."
It means that customers can - as is now the case - book their seats on the airline's website.
But as well as that, they will have the option of the firm sending a barcode to their mobile phone that will enable them to go straight through security where the barcode will be checked by the latest technology, and again at the boarding gate.
"It will be completely paperless and will fast track anyone who wants to use the system," said Ms Morgan.
"It will be particularly convenient for business travellers, who - if they finish their meetings early or late - can simply have their PA change the details and have a new barcode sent.
"There will be a different barcode, of course, for each journey, and the service will be available on all our eight daily flights to Heathrow in London.
"We have made a huge investment in the technology for the scheme, and with the flexibility of the Northern Ireland traveller the George Best Belfast City Airport is ideal for our pilot scheme.
"We are the first airline to offer the service and we are confident it will roll out to the rest of our flights.
"It's an exciting development in technology and will certainly cut down on airport waiting time."
