It's not a robust business model, i'm sure the idea looked great, get a 100 people on each rotation, all paying £1000 each, EASY..... obviously not...
Dont forget the published £1,100 fare is the SAVER rtn.
Standard fare can be £1,900 rtn.
FLEXIBLE fare starts £2,200 rtn.
On some late notice dates ONLY FLEXIBLE fares left or made availble.
Assuming 75K rotational cost - does not mean 75%LF needed to breakeven as you might suggest.
Its also a very quiet period for LON-NY. Zoom Airlines UK have stopped operating their scheduled service during this period - 60%LF in Feb for SIL sounds quite good! Market picks up again from March into April.
One of the two new additions will be needed to cover a C check as detailed in a recent trade report.
