ATH - BEG in C
 

Wanted to book a seat in biz class on this route... but can't find any seat, never. A3 does not propose C class on De Havilland DHC-8 400?

Correct - this is operated by OA, and all their aircraft are only configured for Economy.

oh isee... bad (-
This applies to a lot of routes in fact... including the 2 i was interested in : BEG & SOF. For BEG it's a 2hours+ flight, should be nice from them to review this...

There is no C either on A3 operated flight ATH BHX on a 4+ hours flight...

Strange, indeed, for Birmingham, not so strange for Belgrad. While the former uses an A320, the latter is a DHC-8: a narrow "tube" with 4 seats across...

At twice weekly, summer only (well, late March to Early October), BHX is aimed squarely at the tourist market. Done this flight a few times. Business class would be nice but I wouldn't be paying for it - just using my free vouchers. As it is I'm quite happy - I get to sit is row 1 but just don't get the extra service and they're never that full. Isn't the MAN flight Y class only too?

Yes, Manchester is Y only too.
