While I've been faffing with these tickets and prices I've noticed that New Economy is rarely available. Now I'm a bit cynical as the only option to travel with bags is to use the Plus tickets which cost a fortune.
For example NCL to NCE 26/7 returning 28/7 for two adults -
BA Club Europe £877
Flybe Plus £2461 'kin hell!
Essentials is £920 and that's hand baggage only!
