I've paid extra for First Class train tickets for the last few years for three reasons: my mobility has been very decreased and I'm unable to stand for long (but unable to qualify for a Disabled Railcard); my immune system is also shot so I appreciate that it's more spacious; and I can work on my laptop. Basically I pay because it's quieter and cleaner.
Over the last month or so, every time I've travelled the First Class carriages have been full with families, especially young babies and children and OMG ALWAYS listening to ipads and phones without headphones - and I suspect this is because of apps like Seat Frog that buy out the First Class fares and offer them cheap.
First Class travel is pointless IMO if it's as noisy and full of noisy families. Is there any point to it if this is the case? Has anyone else noticed this lately?
