I think it is shocking that this woman had to stand. Ok she may not have asked anyone but tbh was assuming that she did. She was wearing a badge though so someone could have offered. I would always offer a seat to someone who needed it more whether pregnant elderly or with a broken leg etc. I think it is human decency. In have spent most of my working life not pregnant and traveling on trains and have been happy to do this. I find it hard to understand the attitude of "tough luck" that seems to prevail on mn. And ffs not all of the passengers around her could have also had some sort of medical condition. I think we should all think more about taking care of one another and less of the "why should I, I didn't make you pregnant?" mentality.
Not sure about the first class upgrade. I'd never heard about it, although don't have a season ticket. Surely it isn't necessary though? If you are pregnant and feel unwell on packed train I'd have though you could just sit in first class and explain if necessary. Can't believe anyone would fine you - I have risked it lots of times.
In fact I have bought first class tickets towards the end of pregnancy because started to feel v sick on trains and was fussy about where I sat. But I don't travel everyday and not always into London so I don't know how pricey this would be. Also sme people just can't afford it and that doesn't mean they need it less than I do...
I have been thinking that if we won't accept that pregnant women )among others) need to have a seat and if possible we should give it to them, do we really want to pay for maternity leave from day 1? Not an attractive proposition IMO!
