Hi,

I recently flew LHR-DEL on AI, and the flight was 3h45 delayed on arrival at the gate "due to late arrival of inbound aircraft". So, doesn't qualify for the "big" compensation (€600 for a 4 hour delay).

Two part question:

• I've seen a number of references that a 3-4 hour delay qualifies for a €300 compensation (I'd link, but first post...), but I can't find a reference to this being the case in any official documentation, including the UK CAA's website and crucially, the regulation itself. Does anyone know where this rule is actually defined? I'd like to make sure I've done my homework before filing a claim.
• Does anyone have any experience actually claiming EC261 compensation from AI?

Thanks,
Martin
