It isn't a matter of A359 vs. A346 capabilities but about how quick the recovery is, If it is quick enough to restablish at least 1xdaily service to IB's primery markets in US & LatAm, 28 frames won't be enough.
As said in my first post, 28 frames is roughly what's needed for one daily EZE,LIM,SCL,BOG,UIO,GRU,MEX,ORD,JFK and MIA.
I don’t know anything I’ll admit about IB but it’s sad to see the A346 retired early, I flew on a brand new TG one AKL-BKK in 2006 in Y, so comfortable! That’s more the airline configuration but 2-4-2 is great.
Are there other long haul routes though we are talking about in an initial post covid schedule for IB? The mentioned ones would need 17-18 aircraft, certainly no where near 28, that’s allowing 1 each for ORD/MIA/JFK and 3 each for the South American routes.
My expectation pot-covid on IB long haul is:
1xdaily EZE, LIM, SCL, UIO, GRU, BOG and MEX - 3 frames each - 18 frames
1xdaily ORD, JFK, MIA - 1 frame each - 3 frames.
Although not mentioned in my first post, assuming less than daily service to SJO, PTY, SDQ, HAV to be resumed at some point - 6/8 frames.
There are the 28 frames ruling out resumption of JNB, PVG, NRT or a second daily JFK, MEX or EZE.
