First stop - Vienna
Very sleep-deprived, I woke up at 4AM to get ready for the trip and catch the flight to Vienna at 11:05. I took a taxi to the train station from where I headed to Belgrade. After an hour's drive, I took a bus that goes directly from the central train station to Nikola Tesla Airport. At the airport, I waited for a short period before the first check-in counters opened, but I immediately received tickets for both Vienna and Bangkok (flights via Austrian Airlines).
Just before takeoff, a slightly stressful situation occurred. Apparently, the plane was "too heavy to take off," so they asked over the intercom for a few passengers to voluntarily take the next available flight, with a $150 voucher and some other minor benefits. I didn't fully follow the situation, but since we took off on time, I assume someone had to do it. Thank you!
I am currently typing this from Vienna, sitting at one of the hundreds of gates - mostly empty - and drinking water that costs 4.9€... I "smuggled" 180g of peanuts and a Snickers bar from Serbia, so at least I won't have to spend 8€ on a sandwich the size of an average fist. Looking forward to the airplane food.
