Sorry but this may sound like a silly question but can I take a suitcase onto the plane? The reason I ask is that the Emirates website states

"First Class and Business Class customers are permitted two pieces of carry-on baggage: one briefcase plus either one handbag or one garment bag. The briefcase may not exceed 18 x 14 x 8 inches (45 x 35 x 20cm); the handbag may not exceed 22 x 15 x 8 inches (55 x 38 x 20cm); the garment bag can be no more than 8 inches (20cm) thick when folded. The weight of each piece must not exceed 7kg (15lb)."

My cases is within the guidelines but I cant remember seeing suitcases on previous flights so thought I'd ask. Usually I take a rucksack but on the previous 2/3 flights my large suitcase hasn't made the connecting flight from DBX to BKK.
