HeartyMeatballs Sorry, but you originally said "...if my flight diverts because of a medical..." and that was the sole point I addressed. Diversions are exceptional and on that basis, I'd certainly support an airline's according refusal to pay compensation.
ExXB Agreed. Hopefully, no-one with a modicum of even near-sanity would question a Captain's decision for a medical related diversion. I'm entirely with you on that!
