You keep going on about how much people have paid, but what about the fact that I've booked weeks (maybe months) in advance?
This argument has been had before on here in a thread where someone complained about reserved seats (which they hadn't done); the consensus was that the poster could have reserved a seat if they had really wanted to. You seem to want to abolish the entire reservation system to benefit people who turn up at the last minute and with the money (if it's even theirs that they're spending) to buy expensive tun-up-and-go tickets.
I don't feel that booking well ahead particularly outweighs the substantial difference in price being paid. It is still a heavily discounted promotional fare and I see no clear reason why it should offer benefits above and beyond what a full fare-paying passenger can expect. If I go buying bargains at huge discount I wouldn't expect to also get preferential treatment, you don't generally get both in the same package.
I have no wish to abolish reservations, I simply feel that they should be used fairly. At the moment the reservations system is almost entirely the exclusive preserve of the Advance ticket purchaser, and is barely promoted at all to those travelling on anything else. The expectation amongst most travellers is that it's pot luck. However, when you go on-line and book your bargain Advance ticket, a seat is provided without you even so much as asking for it.
A much fairer system would be a box appearing on your screen when you book the Advance, asking if you wish for a reserved seat, and adding an additional charge for it. Nothing major, maybe £2.50 or so, hardly a big expense considering the low cost of your ticket. The same privilege should be promoted at stations and so on so that others can also take advantage, again for a small fee, perhaps slightly less as you are not using a heavily discounted Advance ticket. Agreed, you would lose the flexibility offered by a standard ticket, but I still feel that many would take advantage. Many people still chose to buy ordinary 'SVR' tickets and suchlike rather than Advance, even if they know which trains they intend to use. We would also doubtless see a reduction in Advance users opting for a reservation, as many would prefer not to spend the extra couple of quid, and quite a few don't use them now even when they're free.
The issue here is that quite frankly we have too few trains with too few seats available to just go dishing them out willy nilly. Whilst it might not be universally palatable, the fact is that a
guaranteed seat is a luxury, and it is therefore reasonable to treat it as such. Bear in mind that even those paying an enormous premium to travel in First Class are given no promise of a seat, and the situation with Advance reservations really does start to look farcical. As I said before, TOC's are also guilty and they need to play their part by not offering so many Advance tickets on trains they know are excessively busy with regular commuters, but that's an issue to be taken up elsewhere.
