If that letter is genuine (which is still open for debate as far as I've seen) :-
Manchester City is pleased to offer a group bookings service to help you purchase tickets for Men’s and Women’s home matches in each competition at the Etihad Stadium and Joie Stadium this season.
Bring your group to the heart of the action at the Etihad Stadium or Joie Stadium and enjoy a world-class matchday like no other. Whether you’re planning a school outing, corporate experience, football club reward, or a memorable day out with friends, Manchester City offers exclusive group experiences tailored to suit every need.
You will receive a bespoke booking process and a dedicated account manager, amongst a range of other exclusive benefits.
To qualify for group ticket access, your party must meet the following criteria:
• Group Size: A minimum of 10 people attending the same fixture.
• Booking Purpose: You must be booking on behalf of a recognised group such as:
• A school or educational institution
• A youth or adult organisation (e.g. football clubs, community groups)
• A business or corporate outing
• A tour operator acting on behalf of a group
• Or a personal group of friends and family planning a shared experience
No indication of cost but they certainly don't "give them away" as some have been claiming. I'd guess there's a limit on maximum numbers.
This thread is just rage bait, whether deliberate or not.
