What are the major obstacles remaining (if any) before they can take money on credit cards for tickets ?

Finding some routes that they can make any money on.

Just convincing the public that they want to fly between Shoreham and Alderney…

A new website seems to have gone live with a claimed facility to book tickets.
It doesn't seem to work well with mobile phones though - best stick with using something with a larger screen like a laptop.

The back end for booking tickets seems to be Air Kiosk. Seems a little ropey to me, and maybe not as easy to use as some other booking system providers. I'm struggling to understand what their flight schedule will be

That said, once I see them having operated a few days' worth of flights on FR24, I hope to be able to support them

Flight Schedule ? Once in a blue moon, I should think !

A report in the Guernsey Press this week stated that Air Alderney will acquire a Trislander for Alderney operations! :ugh:
I'll refrain from posting what I said when I read the article.

This was announced in a Facebook post
which claims that the aircraft will operate around the 'Chanel Islands' [sic] from 'Q4 2022'.

With only seven airworthy aircraft left in the world currently to choose from, all in the Caribbean, it will be most interesting to see which airframe turns up... if it does. (Given AA's previous history of announcements which don't come to pass, it would hardly be surprising if nothing ever does.) If it did, it would be the last and only example of a type - whose manufacturing finished around 1978 (the aircraft completed afterwards were effectively kits) - flying in the UK, Europe and the northern hemisphere.

Aurigny's experience from 2013-17 suggests that it hardly will be straightforward to keep a Trislander airworthy on a sufficiently reliable basis to operate to any schedule.

They won't have to keep a Trislander airworthy , because it isn't going to happen. This is a fantasy airline with make believe aircraft & non existent routes.

A fantasy airline with an aircraft an operating licence and an AOC.
I see you still don't do any research before posting

Bean, I know all of that but, regardless, it is a fantasy airline. It may have an aircraft & an AOC, but in the last ten years of following its "progress", it has never operated one scheduled flight, or carried a fare paying passenger on a scheduled flight. It has no routes or licences & the one that it DID have, Alderney to Jersey, never operated one flight because, surprise surprise, shortly before it was due to start they discovered that the licence had expired! Never mind, they were going to resubmit an application: but I don't think that ever happened, either. In my view, it is a fantasy airline.

6 months on, and are Air Alderney any nearer to being a "real" airline ?

And just eight days until the beginning of Q4, when Mr Brem-Wilson has committed to having a Trislander in operation. There are no airworthy Trislanders in North America, Europe or Asia at the moment, so expecting great things and a long ferry flight up from the Caribbean in the next week. Exciting times.

(see post #27)

Still not a fantasy, bean ?
