Bit of an update that might help, following 2 hours in the phone queue today.
1. At the moment you can have as many friends and family as you like as long as they have a membership number. However, a limit will be introduced at some stage.
2. If you have kids who you buy tickets for, when you buy them, the kid's ticket will be added to your wallet and can be accessed / shown on your phone. You do not need a separate phone for the kid's ticket.
3. For season ticket holders, if you want to relocate for any game (for example if your Mrs or one of your kids is coming and you want to be sat next to them) you can only do this by ringing City and can only do it in the 5 days preceeding that game. This cannot be done online.
4. Adults need either vaccination proof or a negative LFT for every game.
5. Under 18s don't need any proof whatsoever re Covid status.
The kid said there were 123 people in front of me in the queue and City have been absolutely battered with confused supporters and complaints in relation to the mobile tickets thing.
