Anyways........... what everyone is saying including Sami doesn't really tell me anything, it doesn't change the facts of what happened with these routes.
As near as I can tell........I still did everything right, I still don't know what went wrong other than not flying to Heathrow.
And based on what you've posted here, you didn't do everything right. But it's very hard to tell exactly what you did wrong, because we're basically guessing based on incomplete information, without knowing your scheduling, your prices, your actual supply vs the route's demand, or how accurate you are about the 'insane profit' of the airline in Chicago. Your daily profit numbers that you put when listing your planes make me think you've done something badly wrong, quite possibly you've got flights too close together. Flying most days twice will result in slower growth than flying two different routes (e.g. HNL, which memory tells me is big) once each, unless your single route has huge demand from day 1.
The research I did of Narita to LAX vs Chicago to Heathrow showed Heathrow had 20% more demand which I thought was not a big difference and the fact I have no competition in Narita made Narita a logical choice.
So I hope some of you can understand my bewilderment when I saw what a massive difference in loads, sales and profits there is between these two routes once I started flying..
How do you know that your view of the other route's loads, sales & profits is accurate?
Narita is a logical choice. Very large longhaul airport, with heaps of routes both west & east, it's an easy airport to make money in.
The only thing I can think of was that Chicago to Heathrow is a shorter route and can probably be flown on a daily basis using the same plane.
Where Narita to LAX is much longer and therefore has to be flown with flights lasting over 24 hrs and requires multiple aircraft to achieve consistency.
It was a challenge......but I achieved a consistent service using several planes with all the flights landing or taking off during prime time.......5 am - 10:55 pm.
It appears the most profitable routes are ones you can fly roundtrip within a 24 hr cycle........this can make a big difference.
No, it's not that the routes are significantly more profitable, it's that they're more likely to be run on an efficient schedule. I suspect your schedule is not very efficient.
Again, it should be easy to build a big airline having Narita to yourself. The answer isn't that you're doing everything right, but they're getting benefits you don't have. The answer is you're making mistakes that you don't realise. Posting a thread here trying to work out what boost of theirs to blame won't get you anywhere. Putting in a mentor request to help you learn what mistakes you're making, and learn how to not make them/do things better, that might help.
