I have a flight coming up in September, and at the moment there is no upgrade availability, but I'm also meeting a friend and we're flying TXL-AUH together on the same flight. I was hoping to try and use 2 of my upgrade vouchers to upgrade both of us, but he booked his flight via Etihad, so it's sold as an EY flight. If space is available, do you think they'll allow an upgrade? I emailed the platinum desk, but the answer was vague and ambiguous, and only clear information was, "No upgrade available at the moment".
