Ryanair has announced details of its new business product, which will offer extra services to customers who pay a higher price for their plane ticket.

Those using the airline’s Business Plus service will be given priority boarding, a 20kg allowance for a checked-in bag and the ability to change flights up to the day of travel.

Ryanair also said the service would allow for fast-tracking through security at some airports including Dublin, London Stansted, Manchester, Brussels Charleroi and Milan Bergamo.

Customers will be offered the service, along with the standard ticket option, when booking their flight online.

The airline has also announced details of its summer 2015 schedule for Dublin Airport, extending its recently-announced winter service to Brussels Airport into next year.

Ryanair said it would have a total of 81 Dublin routes next summer, serving around 9.2m customers over the course of the year.
