Not having some specifics about the airline involved...
I would say -

(1) Travel market - How low, "low cost" airlines have to go to to fight competition...?
How far will the "low cost customers" accept to be charged $5.oo for peanuts in premium class...?
(2) Global market - Cabotage by "Chinese Airlines" in i.e. European or US domestic sectors...?
That will be the case in, say 10 or 20 years.
Air China operating LHR to MAD, or from JFK to BOS...
Will BA or LH still exist facing that competition -
And will you accept Chinese scale employee salary...?
