Thanks. I have paid the £46.
I agree with the sentiment over paying for to fly further forward on the plane. In fact, for several years, I did pay to fly in Premium Economy, when the extra was only around £300, admittedly booked well in advance. Divide that by 24 hours for a round trip and it was acceptable.
Then post covid, every time I look, it is ~£1000 extra to fly in Premium Economy. Which works out at over £40 per hour.
So I'm back in economy for now.
[Incidentally, about 10 years ago, I used to get an economy emergency exit seat over 90% of the time, just by being the first to check in at the airport. That stopped working with online check in.]
Due to Covid and other disruptions, I've also tried some indirect flights. I dislike flying via the Middle East, as it means waking up and walking around some enormous airport in the middle of the night when I want to be sleeping. If I must go indirect, I'd prefer to transfer in Europe.
