Boston to Doha flight was great. After my first flight before I got into my second flight Doha to Dhaka they took my carry out bag and put in the plane as a luggage. All my valuable was in my carry on bag. It did not seem good to me because I was worried about my valuable in luggage. Finally, I reached my destination and got my luggage safely nothing missing. My urge to Qater Airlines to change this type of unsuspecting situation. Thank you
