I flew from Seattle to Dubai on 09/08/2024 in business class. While the flight itself and the food were excellent, my overall experience was significantly diminished by the conduct of the cabin staffs. The male flight attendant serving my section displayed a consistently cold and unfriendly attitude, which, though unpleasant, I could tolerate. However, his actions during the flight were unprofessional and rude. On multiple occasions, he kicked my feet without offering any apology, which was already unsettling. What was most concerning, though, was how he handled the mattress storage. For some reason, they had stored a mattress in the overhead bin right above my seat. Throughout the flight, he would repeatedly access the bin, even while I was seated, leaving it open for extended periods.

This not only prevented me from accessing the bathroom, but also made me feel like I was sitting in a storage closet, as though my comfort and experience were secondary to their operational needs. The level of unprofessionalism and disregard for passenger comfort was truly disappointing. I strongly suggest Emirates revisits its staff training to ensure higher standards of professionalism and basic courtesy.…
