the A359 with 300 pax on board (AI configuration)
has that been confirmed?
to perform BOM-LAX/IAH/DFW nonstop without a payload restriction
There's no aircraft extant nor planned that could perform any such route "without a payload restriction," the question is, if they want them done nonstop, what payload will they opt to take.
Your overly-simplistic blanket statement of "no aircraft they have can do it" remains incorrect.
Pre-covid, Cathay's A359 faced payload limits flying ORD/BOS.
As any aircraft flying such a route would. Again, there's no aircraft in the skies that's going to fly HKG-BOS with zero limitations.
Yet, CX found success doing it, without even the highest w/v of that aircraft.
9W lost millions flying via BRU to EWR/YYZ/JFK because their revenue management and sales strategy was bewildering. They were selling on average US$ 900-950 round trip tickets to/from India when oil prices were sky high. I know because I was involved in pricing benchmarking against them as they were a competitor for a few years before I moved to Lagos. Remember oil prices were for two years (I think 2013-14) were averaging $120-140 per barrel and yet 9W had very low fares.
You're confusing that with 2008-2009.
In 2013 and 2014, oil averaged $108.56 and $98.97 respectively.
But regardless, what'd be different now?
Oil's sky high, isn't likely going down any appreciable degree any time soon, and the ME2+TK are infinitely more powerful over the Atlantic and regionally, than they were back then.
SQ's A359s nonstop to JFK seat 161 pax only whilst AI's shall seat 300+ so nearly double the amount hence much more fuel to uplift etc. Definitely not a fair comparison I'm afraid to say ! Even the 253 seater A359 would still offer 20% less on board capacity than AI's A359.
So what? DL has 2% more seats than you allege AI will, yet they fly a route similar to BOM-LAX while departing at 5600ft elevation
BOM-Texas and BOM-LAX are around 17:00-17:30 hours block time and slightly more from LAX returning back. There is no realistic way the A359 can be able to fly that with a full payload in AI's cabin configuration more so especially in winter season !
So then guess what AI would have to do if it wants to serve those routes. You act like this is rocket science..... it's really not.
