3 hours trying to get through security at Heathrow, 7 hour flight to Dubai with cramped leg space, a few hours in Dubai International Airport (lovely place, but a shame I couldn't leave the airport, plus it was past midnight at Dubai time), 8 more hours going from Dubai to Hong Kong, no proper sleep, legs killing me due to limited leg room, and it's 34 degrees Celsius.
Travelling isn't all great.
