Will boarding cards for outward and/or all flights be issued in advance and if so when and can they be shown on my phone as I do not have access to a printer ?. Thanks 

Thanks so much for getting in touch. Your final documentation which is issued 2-3 weeks before travel will inform you whether you will be able to check in online or on arrival at the airport. If you are able to check in online there will be the option to download your boarding cards to your phone, or the check-in team will be able to issue physical cards to you.

Best wishes
