Many will have read about Niceair having "issues" with the CAA around their flying between Akureyri in Iceland and London Stansted. If interested, the main business newspaper in Iceland has some good coverage (Google Translate works well) -

It seems that to satisfy the post-Brexit bilateral, one needs a UK or Iceland based airline to fly between Iceland and the UK - a wet lease from an EU carrier seems to attract too many queries from the CAA. I realise Niceair probably don't have the cash to lease in another aircraft, but if they did have the cash, which airlines have suitable aircraft to fly 1,000 nm over a lot of sea and might be interested in operating a wet lease for Akureyri - London ?
Icelandair wouldn't want to help a competitor, while BA, Easyjet, TUI and Wizz UK are all struggling to operate their own schedules, Jet2 are leasing in aircraft from other airlines, Eastern haven't got anything with the range, and I can't see Ryanair UK being interested.
So potentially what airline in the UK or Iceland has suitable available aircraft, and would be interested in doing some regular passenger wet leases between London and Akureyri without demanding a huge pile of gold ? Loganair ? Titan ? Anybody else ?
In the absence of a suitable airline, is the CAA (or DfT) able to grant an exemption to a bilateral to allow an EU-based airline to fly the route as a wet lease instead ?
