Part of our service for passengers needing assistance boarding is luggage assistance wherein we take care of checking your bag through free of charge and issue you a priority assistance pass to help with collecting it at the end of your journey. We will check your bags at the originating airport during pre-boarding, ensuring they will be carefully loaded. This same assistance pass will ensure that our crew knows to keep you comfortably seated at the arrival airport while we arrange to assist you, so you won’t feel rushed.”
