RE:Vancouver - Sydney FlightRouge you once again are talking out of your azz. You are comparing apples to lemons unless you lay down some specifics. For example, number of stops, layover times etc. It makes a huge difference I can fly same date for $1000 less....
Additionally, you have to account for other factors, such as fuel costs, labor costs, covid screenig etc costs. How many planes are in the air, how many on care and maintenance because flights were not full so 1 goes out instead of 3 etc.
To say no matter what it will be very profitable! Once again you spout meaningless numbers. Needless to say you are still struggling with understanding business costs let alone proper comparisons and profit models!
