## FAQ **Q: What currency does London use and how far behind Vietnam is it?** London uses the British Pound (GBP) and English is the language, so there is no translation barrier for most travellers. The city runs on UTC+0 in winter and UTC+1 in summer, putting London roughly 6 to 7 hours behind Vietnam. When it is 7pm in Ho Chi Minh City, it is early afternoon or lunchtime in London. **Q: Which area of London should I stay in?** For a cheaper base in London, King's Cross runs about $40–80 a night. If you want to spend more for a more central riverside position, South Bank sits around $80–180 a night. Either way, London's Tube network is what really determines convenience, so weigh nightly price against how close a station is to your door. **Q: How long is the flight from Vietnam to London?** Flight time depends on the route and airline. Direct flights are fastest, while connecting flights through hubs like Bangkok or Singapore may add 2-4 hours of layover. Check details on Pingsme to compare times and prices between direct vs. connecting flights. **Q: How far in advance should I book for the cheapest price?** According to Pingsme data, the best prices typically appear 3-4 weeks before departure for domestic routes and 6-8 weeks for international routes. Avoid last-minute bookings as prices can increase 50-100%. Enable price alerts on Pingsme to get notified of price drops. **Q: Does checked baggage come with budget tickets?** Most budget airline tickets (Vietjet, AirAsia, Jetstar) only include 7kg carry-on. Buying checked baggage online before the flight is usually 30-50% cheaper than at the airport. Pingsme displays baggage costs when comparing tickets so you can calculate the true total cost. --- Source: https://pingsme.com/en/blog/london-cheap-flights-1790837814615
