That doesn't reflect the reality of things like the way you make it seem.
You haven't even considered other factors like BOM having way more options/seats on int'l markets which would mean pax have other ways to get to those above mentioned cities you have used as a reference. Hence, BOM would have seats available at last minute while BLR wouldn't, but that doesn't prove the latter has more demand.
That logic would be fair if the seat count or frequencies to Int'l markets were almost equal out of the two airports, which it's clearly not.
BA has 18 weekly flights from LHR to BOM , just 7 weekly to BLR.
LH has from BOM a total 14 weekly to Germany (FRA+MUC) plus Swiss 7 weekly, so total 21 weekly from LH group. BLR just 7 weekly from LH group.
14 weekly non-stop services from BOM-EWR on Star Alliance carriers (AI+UA). Whereas BLR has none, and no non-stops even to USA. AC operates from YYZ on and off to BOM too.
SQ has 21 weekly (all WB's including an A380) , CX 14 weekly (77W's) , EK 35 weekly (including an A380) and such, while BLR receives far fewer seats from those carriers. The list of such carriers goes on from BOM , many of which don't even serve BLR.
So last minute availability of seats out of a city or the price is not a defining factor to show which airport's more popular or having more demand. If last minute fares on flights (or its availablity thereof) from Rajkot to Amreeka cost more than BOM to Amreeka, we can't apply your flawed logic of RAJ having more demand than BOM for US flights. It's a factor of number of available seats out of the city. Rajkot has barely a single daily to BOM/DEL each, so it would cost more at the last moment obviously because seats would be booked out on such limited inventory.
BLR still has comparatively has far fewer int'l seats than the big two Indian airports , and is even lesser than MAA as per the last data. Heck, till a year back or so, even COK had more int'l seats than BLR. So your data goes on to prove nothing.
Also, if BLR airport authorities go on harping about more premium demand at their airport than any other Indian airport, well, thats their PR job to woo more airlines. But the airlines are not fools, they have access to all the valuable pax data and know more about each city's potential than what BLR airport authorities claim.
Well, well, well, I' m afraid you missed the whole crux of the data presented when you came up with your own hypothesis. I am even more surprised that the two individuals that the data was directed at have cheered your response even though they exactly know what the data was pointing to.
This particular discussion was started when I merely stated that BLR commands fare premium in last minute J class travel to India from US. This fact was disputed by two posters and one of them brought in BOM for comparison. I then presented data with a specific set of conditions that are applicable to last minute J flier. Under that condition, BLR has continued to command premium over BOM.
Your argument that EK and BA have more capacity into BOM has NO relevance
to the fare data presented. A last minute J flier will fly the shortest possible schedule on any given airline. Between the city pairs presented in USA to BLR/ BOM, it doesn't matter if EK has 5 times a day schedule from DXB-BOM, since a J class traveller will NOT prefer to take a schedule that will take him/her 28-40 hours to reach BOM over a schedule that is closer to 20 hours. Given that, why on earth would I include a ORD-BOM flight on SQ for fare-data comparison when the shortest option is close to 50 hours
or ORD-BLR on SQ when the shortest option is close to 64 hours
of travel ???
So, in the data that has presented it has been clearly stated that the price comparison has been on flights operated by the same airline on their shortest flying duration with their flagship hubs; a fact that you clearly MISSED. So I will stick with my data that BLR commands a fare premium and seat-shortage in J class travel to India. No one on this thread has presented any data to prove otherwise. This simply proves that BLR is underserved. Not making any judgement about the level of service in BOM or any other city in India, just stating the plain fact that Bengaluru is underserved. Again, your point of BOM having a plethora of longish 30 hour+ schedule on various combinations of airlines is applicable for Economy class. That's a discussion for another day.
Also, just because airlines are dumping capacity in a certain airport doesn't mean that they are profitable. Further, average fare-data between city pairs is strictly focused on pricing. If a city pair has lower average fare because of competition it still
implies that the fares are CHEAPER
over another city pair that has HIGHER average fares because of lower competition. Higher average fares are always better for airlines more-so when stage-lengths involved are similar.
You bringing Rajkot and Cochin into a discussion that had everything to do with USA-India J class fares tells me that you simply have no clue about the crux of the debate. Also, please avoid making cheapshots by stating that the BLR airport is doing a PR stunt in promoting the airport. No airport in the world can simply do a PR stunt when you don't have numbers on your side. Just ask Hyderabad !!!
I reckon that you (and many many others posting in Indian Aviation) do some research on O&D data between city pairs that have been referenced, YoY O&D growth, YoY traffic growth and fare data. Besides, there are are subscription sites available which clearly list out inventory availability and pricing for premium classes. Take a look at them. May be then, you will understand what is being talked about.
I can present some more data that are hard facts. But, clearly there is an anathema on this thread with regard to any FACTUAL DATA that is presented. It is hysterical and comical. Period.
