I had not so great experience flying from Dubai to Doha the other day. I had to cross multiple security checks although I never crossed over to the land side. The Doha airport staff are lovely but the system they have in place of making everyone do multiple security checks is absurd. I was checked on take off from Dubai, why check me again in Doha? I was not leaving the airport. I feel like I could've simply been allowed to get on the next plane without another intrusive security check. Again, I am not blaming any staff at Doha Hamad Airport the staff are simply some of the nicest kindest most helpful people (the African staff are so much better than the Indian staff).
