Other Middle East and Africa Frequent Flyer Programs - AMS-CMN-AMS Royal Air Maroc Y or C? Advice?

I am flying to CMN for a wedding in November. My transatlantic sector is from PDX to AMS on DL Business Elite. Question - is it worth an extra $600 to fly Royal Air Maroc business class from AMS to CMN return? I've never flown AT before - have no idea what a narrow body business class service might be on this carrier. Is there enough extra space and service on this relatively short flight (3.5 hours) to justify the cost? Please advise.

I flew LHR-CMN-RAK wtih RAM in October last year (for a wedding in CMN (very good)). The C-seats are US-style F-class with about ca 36/38". The food was very good; three courses (incl. Foie Gras), decent wines, Laurent-Perrier champagne, fruit cart and Moroccan mint tea. Service was relaxed and constant. I believe they serve dinner in Y and have soft drinks as well. I bought the ticket as I missed my flight from Gatwick - had looked at buying it for about £500 in advance but paid £500 for the one-way instead. If $600 is a stretch for you, don't do it, but if it is not an issue, I'd do it.

Thanks for the advice - if AT has seats equivalent to US domestic FC, it's well worth the $600 difference. The last time I flew from LHR to CMN a couple of years ago (I think it was a subsidiary called GB Airways, or some such), the business class cabin was essentially the same as economy class, although I guess there may have been 5 across seating. Cramped and definitely not worth a premium. I'll try AT based upon your recommendations - thanks.

Do be sure though that you do not book an Atlas Blue codeshare - they operate with a C class as well, the difference only being a different meal. It should be possible to tell this from the booking engine (I think a low flight number).
