I'm a seasoned traveler. Both for leisure (usually Economy) and for work (Business). As lots of people have noticed, flight prices this year are bonkers.
One other thing that has changed, is the price of Premium Economy cabins. Whilst previously they'd be say £150-300 more each way for a long haul flight, now they are easily over double the economy ticket.
Who actually would pay £2-3k in Premium Economy to Singapore or Bangkok, when Economy is £1k.
Before people say "I DO", I don't mean those who pay £150-300 more, or get them on sale, or use points to upgrade... I mean people who seriously think paying twice the price of an Economy ticket.
