Thus conclude my very first Europe backpacking trip. We chose QR and transit in Singapore this time because flying directly to Europe from Taiwan is unreasonably pricey (the same for CI, KL, BR, TK, EK). So we decided to buy Singapore - Europe open jaw ticket plus a LCC to and return flight from Taipei. I definitely hope more airlines can start flying to TPE, increasing the competition and benefiting the flyers.
