There is still a big market for full cost airlines as Lufthansa( A321), Air France(A319, A320) , KLM (B737) and SAS (MD-80) have shown, they have wiped the floor with Citiexpress, the only exception being Iberia which is a Noworld partner.
Flew to Paris with Citiexpress on an EMB145, nice enough aircraft but the guy sat next to me was quite a large person
and by the time we arrived at Paris he had to be peeled out of his seat
Return should have been on a RJ100 downgraded to a EMB145 due a storm at Manchester and re booked with Air France
on an A320 much more room and a lot less
clostraphobic ( hope I`ve spelt that right)
and I`ve got to say Air France pulled out the stops to get us back
If you are travelling on business you want a decent service where you arrive in a fit state to go to a meeting and the flexibility to change a booking at the last moment if plans change
