Worth it? yes,yes,yes. Earlier boarding, earlier disembarking, getting luggage, picking up car etc. We went this April and felt it was worth every penny as the trip was so much easier than the last time we did it.
In the past we have paid the amount we paid extra for all of us, for each of us to travel by business class. Its not as good as business obviously, but much better than economy. Having said that I think the food was the worst I've had on flight, but I'm not a frequent flyer!
We'd definitely fly PE again, bank balance permiting. You could say think of all the things you could spend it on, but for me it's worth it to arrive feeling human!!
'It is better to travel than to arrive' or so they say!
