Dubai International Airport
Dubai International Airport (IATA: DXB)  is the largest hub in the Middle East and the home base of Dubai’s flag carrier Emirates  and its low-cost wing FlyDubai . In fact, it has grown at such a furious pace that the present terminals are bursting at the seams, especially during the peak hours around midnight.
The Dubai International Airport has three terminals and another one in the making as of end 2010.
- Terminal 1 is the main terminal, used by most major airlines and long-haul flights.
- Terminal 2 serves regional and low-cost flights, including all FlyDubai flights.
- Terminal 3 is used exclusively by Emirates.
Terminals 1 and 3 are directly connected to each other via the airside (no immigration needed for transfer), while Terminal 2 is located at the other end of the airport. Terminals 1 and 3 are models of modern airport design, but Terminal 2, despite the recent renovations, is still reminiscent of developing world airports, with long check-in lines, queue-jumping and every other passenger checking in 50 kg of luggage. Shuttle buses run between Terminals 1 and 3 every 20-30 min. Terminal 2 is not connected by shuttle so a 30 min taxi ride may be your only option. A low-cost option for traveling to Terminal 2 is to catch the metro to a nearby station, such as the Stadium or Airport Free Zone metro stations, and from there catch a taxi to Terminal 2 (should cost around 15 AED).
The airport is famous for its duty-free shopping . However, prices in the airport’s duty-free stores are equal or higher than what you can find in the many malls of the city. One key exception is cigarettes where a carton of 200 is less than USD$30 for most brands. Alcohol here is very cheap, though. Alcohol is also available at an inbound duty free store situated in the baggage reclaim area and what is worthy of note is the fact that cans are on sale there – so you don’t have to lug them from your destination. The amount of alcoholic beverages and beers should not exceed 4 liters of alcohol beverages, or 2 cartons of beer (each consisting of 24 cans, not exceeding 355 ml for each can or its equivalent).
Taxi: Most visitors will opt for public taxis from the airport, which are readily available just outside arrivals, which use the meter and start at Dhs 25. Taxis are on the left when you come out of terminal 1.
Public transport: Terminals 1 and 3 are served by the Dubai Metro. There are also buses just steps from the baggage claim, the most useful for visitors being lines 401 and 402 (Dhs 3), which go to the Al Sabkha and Al Ghubaiba bus terminals respectively.
XNB ETIHAD BUS TRANSFER FROM AUH

Al Maktoum International Airport (Dubai World Central, DWC)
Al Maktoum International Airport, better known internationally as Dubai World Central (IATA: DWC)  opened for passenger transportation in October 2013.
