………...all of which is great but if you read what I said again you will note that I was referring specifically to the likely habits of
business/1st class travellers in the context of the point of the original post, which was the slight reduction in the ludicrously high price of 1st class Anytime/Off peak returns, and putting forward one of the likely drivers of that reduction which is the availability of quicker and cheaper flights which would appeal to Business travellers as an alternative. You've also helpfully highlighted the earlier arrival time in London by air too.
I know that the concept of competition is a totally alien one to those who work on the railways, but it does exist
I've removed some of the quotes, but absolutely, you may well be right in that that is a part of the reason for the reduction. But if you read again what I wrote, you'll see all I am doing is making a comparison between the price of advance booked 1st class rail and advance flight prices, rather than walk-on rail prices versus advance flight prices which is the comparison, even if indirectly, that you were making. I know which
I think is the fairer comparison. The standard class prices were also quoted to give a meaningful comparison as not everyone travelling on business insists on 1st class, just as not everyone travelling by rail on business waits until the last minute to buy their ticket at those (still) eye-watering prices.
The slightly earlier flight arrival at London City Airport is indeed helpful if you are headed for Canary Wharf, but that time will soon be swallowed up if you are heading for anywhere in central London. There is a greater choice of options if you choose to go by rail, and other benefits such as railcard discounts and the ability to pay the difference between your advance rail ticket and the walk on fare if you miss the train you're booked on (what happens if you miss your one-a-day flight?) but no doubt the flight option will be clearly the better option for some.
It would be interesting, and probably more relevant, to gauge the impact of competition from Flybe, to see whether advance rail tickets around the times of their flight are either reducing in price or increasing in number as a result.
Regarding your last point, I've stated before I am personally all for competition from other modes of transport and a genuine choice for travellers, but I will sometimes choose to take the time to point out the benefits of rail that might be overlooked by some for whatever reason.
