Today when I was on the VS website, for no particular reason I clicked on to the "Your statement" link and found this As someone who has had her e-tickets rejected by her email provider this is a welcome addition. Well done VS 
Incidentally I emailed VS during the week as I still hadn't received my e-tickets for either Dubai or Washington in spite of promises that the paper ticket would be sent out. By return I received a reply apologising, offering me 5,000 miles and stating the tickets would be sent out to me within three working days. An hour later the Dubai e-ticket came through (long before I had seen the above link) but a follow-up e-mail said my Washington ticket would be sent through the post. Still waiting!!
