It's wishful thinking here.
LX doesn't have the customer base nor excess capacity to consistently fill 180 to 200 seat A321's to Africa.
The routes to/from Africa are very thin, and with the level of competition that there is now, there is no room for new entrants.
There is no O&D from ZRH and LX has failed to make Cameroon work, transferring those routes to SN.
Look at East Africa where a true bloodbath has LX pricing NBO flights at firesale fares.
If LX could have done it, they would have done a lot more using Privatair.
This is a case of finding a route to match an aircraft, not an aircraft to match a route.
LX better stick doing what they do now, they're super profitable as it is. If it ain't broken, don't fix it.
Taking into account how LX configure their aircraft in a heavy configuration, I'd expect a cabin of 20 to 28J on any 321neoLR they might operate, bringing down the total to 160-170 pax.
East Africa is a tricky market as you have the ME3 and ET/KE who are aggressive on that front.
The same cannot be said for West Africa, where there's a lack of supply in seats and going through DXB makes less sense than for those going to East Africa.
I think for LX the 321neoLR really comes down to a couple of main points:
-Willingness to use the aircraft to recapture some long-haul markets from GVA that are thin but have strong yields. The aircraft and the markets it could serve seem better fitted to GVA than ZRH - but does LX see itself investing long-term in GVA (bearing in mind the short-haul operation is loss making but overall balanced by the profitable JFK flight).
-Willingness to go back into 'traditional' SR markets long since abandoned and either never or very shortly served by LX (Middle East, West Africa)
-Desire to use these aircraft to free up widebody aircraft (eg. NBO/DAR, TLV, YUL, BOS, EWR, DXB/MCT)
-Desire to offer a more premium experience (and try to obtain a premium or be/become more competitive) on some of the longer medium-haul destinations (DME, CAI, TLV)
Historically most of the articles about Swiss that are published in the Swiss press aren't far off and eventually end up happening. The article makes me believe Swiss has defined a business plan or strategic use for these aircraft but still needs approval from LH.
