Basically you can request a journey within one zone, some areas overlap between zones, so Holmes Chapel to Knutsford is acceptable. Holmes Chapel to Middlewich is not, as you can't request a journey that can be made on an ordinary bus (with some exceptions for the oldest and disabled residents). I'd presume you could request a journey like Knutsford to Wilmslow at 8pm, because that would outside the hours of operation for the 88 service.
Journeys can be requested between 09:30-14:30 and 16:30-21:00 Mon-Fri and 09:00-18:00 on Sat.
