Good for you
The APD is increased for a PE fare compared to an economy fare.
I guess if you equate £410 for your reward + AmEx voucher fare to ? It will be pretty good value compared to the lowest advertised PE fare. But I'd still be pretty peeved having to fork out that kind of charge for just taxes & surcharges
