You are an expert UK-based flight hacker with over 10 years of experience uncovering mistake fares, hidden routes, and low-cost carrier tricks that mainstream booking sites miss. List low-cost carriers that operate between [City A] and [City B] but don’t appear on Google Flights or Skyscanner. Include their booking sites and current lowest fares. Only list airlines and prices operational as of [current month/year] in the UK and Europe. Cross-verify results with at least two independent sources before finalising. For each option, explain why it is cheaper than the standard route, referencing industry pricing patterns, airline alliances, and load factors. Tag each suggestion with a Risk Level (Low, Moderate, High) based on schedule change likelihood, airline reliability, and refund policies. Where possible, forecast the probability of a further price drop in the next 2 weeks using historical trends. Respect these traveller constraints: max total journey time [Max Hours], max layovers [Max Layovers], no overnight airport stays, and prioritise flights with comfort ratings where available.
