Perhaps, but I think it’s more route specific. LHR-JFK is probably a bad example as even with the highest capacity jets, high frequency would also be needed because of the demand. But say like lga-bos/dca, I’m sure the airlines could consolidate the hourly flights into a few wide bodies, but that would be a disaster as many folks (myself included) like the flexibility of the high frequencies. Even in a case like jfk-lax/sfo, the us3 could probably save operation costs by using a 380 or 748 on it, but because frequency is prized by travelers on that route, they stick to 757s,321s, 767s, etc. However, since we’re on the QR board, a good counter argument would be doh-bkk. QR has like 6 (7?) round trips to bkk. I’m sure many travelers in both J and Y would prefer a 380 to a 330, old-style 777, or a 787 and some would even prefer the 380 to a 350 or updated 777 and would sacrifice the freedom of frequency to be in a 380 over any of those aforementioned jets as long as they make their connection. I’m sure QR could’ve consolidated those 6 or 7 flights into 3 to 5 380 flights while saving money on operation costs and increasing passenger satisfaction. So perhaps on business heavy routes, frequency is king, but on high demand leisure routes (like bkk), passengers prefer larger capacity jets over frequency?
