The Qatar Airways DLC Terminal resembles an entertainment park with an airport theme. It’s difficult not to lose yourself in the opulence, with duty-free stores fit to bankrupt a small nation and lounges plusher than a five-star hotel. There are so many culinary options that you might need a map to find your way around, and the Wi-Fi is so fast you’ll swear you’ve been transported to the future. It’s a preflight holiday spot, not simply a terminal.
