If money was no object then I'll buy an A340-300 (-500 would be nice, but they're probably a bit heavy) and spend the necessary money having it certified with P&W PW1135G Geared Turbo Fan engines. The idea being to revive the A340 somewhat with the hopes that some airlines will have their aircraft re-engined, prolonging their time in service. Hopefully it might create a viable freighter conversion program aswell. I'd also have some A350 style sharklets fitted.
My A340-300 would be configured to seat ~100 people. The inside will be tastefully decorated (no jacuzzis, or saunas here) with white sidewalls (show up mood lighting best), lots of gentle beige and brown leather (inspired by Etihad's new first suites), dark carpets and no chrome/gold interior fittings. As you enter 1L, you will pass through a generously proportioned galley, past a bar and into the main lounge/dining area. Past the next bulkhead (where there will be a bathroom and stairs to the lower level) will be the main seating area. Here there will be 30 or so Singapore Airlines first suites. Beyond the next bulkhead will be an office (very futuristic looking, like in the French presidential aircraft) and beyond that a bedroom. At the aft end of the forward cargo bay and the front end of the aft one will be bathrooms and crew bunks (like what Lufthansa does in their A340s). In the cargo bay, I'd keep a folded up Schempp Hirth Discus or
The aircraft would be named 'Spirit of Valbonne', which would be written behind the flight deck side windows and will be painted in a livery somewhat similar to Air Tahiti Nui's.
If that didn't work out, I'd fly to Toulouse and write John Leahy a cheque for A350 MSN002.
Realistically though, I actually really enjoy flying commercial, even in economy. I'd be perfectly happy to only ever own a Tiger Moth.
