Planemike. Not a problem. Just turn up with your case and documents. Allow a little more time than in the old days as there are now fewer check-in agents (saves money) as a fair number will go through the machines. If concerned about not having a physical ticket to hold - you might ask a [dare I say?] younger relative to print things out for you. I have worked in IT since I was in my mid-20s so am happy to do this but, I understand, Grandchildren do have their uses in these matters!!
