I'm booked to fly to Munich on Thursday with Lufthansa. I haven't flown with them since 1993, it was very different then. I received an e-mail from the company to confirm my booking, unfortunately I appear to have deleted the e-mail (don't know how as I try to be careful when deleting old e-mails) - luckily I remember the Ref no! There appears no way to check in or manage your booking without the ref no. I am concerned as I have not received an e-mail nearer the departure date as other airlines I've flown with have!
Can anybody confirm, will I get an e-mail prior to 'remind' me to check-in? Or would I have lost everything had I not memorised the ref no?
