Hi guys, i am arriving at DBX from MAD at 7 am (Y class) . I have almost 4 hours until my next flight to PEK. What do you recommend me to do at the airport while waiting? Is there any good place to spot aircrafts or to see the the skycrappers from the airport?

I also would like to know if I get anykind of earphones onboard to enjoy ice or do i have to bring them?

Thanks
