Sapphire by Arriva

[Polo Mint]

RE: Sapphire by Arriva
Why do some routes get special treatment with Sapphire whilst most routes stay the same? Doesn't that cause inconsistencies?

Is sapphire more expensive than regular Arriva services?

It would be better if Arriva added leather seats and wifi to every bus like First Bus.

Route 263 is a busy but competitive route (Metrolink and Finglands), I think it could benefit from these features.
