Dear sir ; I flied with Oman air eight times in 20 days. Yet in my first flight from Milan to muscat I didn't find my luggages. I asked well in aeroport and they told me that it will arrive to Duqm as it was my final destination to Duqm. I was in Duqm as an operation manager and in my luggage I have all my documents and my stamps of company so I couldn't exercise any of the missions I went for because my suitcases arrive only four days after. During my stay without personal effects I was obliged to buy other necessary things such as clothes and toilet products. Yet when I flew again with oman air from duqm to abudhabi they make me pay for extra luggage (4 kg) again 92$ in flight Abu Dhabi muscat + 150 $ from muscat to Milan. This was not safe as al the extra weight was because of the extra shopping Oman air caused me . I blame so Oman air for having caused me lot of delay in my project and lot of damage and extra expenses. Otherwise I 'll let advocate of mine arrange things in severe manners.
