I arrived at the airport and I'm waiting for my flight

I already checked in for my flight and went through security control. At the security control zone, the staff asked me to take off my shoes. The last time I experienced this was at Moscow airport. I also found my gate, and now I just need to wait for my flight and enjoy my time at Da Nang airport.

I was also a little bit confused because I tried to check in online on another airline’s website. My airline was VietTravel, but I tried to check in on the VietJet Air website. I had already tried last week, but every time I got an error saying “Your flight was not found.” So I decided to check in directly at the airport. However, when I arrived at the airport, I checked my confirmation invoice and saw that it was VietTravel Airlines. Then I decided to search on Google for “VietTravel online check-in,” and I found their website and immediately checked in.

It was my fault—I don’t know why I got confused. If I remember correctly, I thought I bought this ticket from VietJet Air, but actually, it was purchased on the VietTravel website. I think I was confused because I was working so hard at that time and couldn’t remember. Also, all my attention was on my work.
