Flew DUB-ORD back in late Feb this year. Yes 330's are used and likely to be -300 series.

Flew business and it was half empty
the same on the return journey.

Laid back service, they don't seem to stand on ceromony, but very friendly in a genuine way.

Food is simple, nothing exotic or anything.

Seats are grey leather, with personal pop up tv screen. Seat movement dynamics, very basic. with no motor drive support. Not the best for anything approaching lying flat.

Despite this was very impressed but expectations were not high too start with ! Great if you can get a consolidated fare. I payed £1760 pounds return from Heathrow !!

p.s Good kit bag
