Why depart from Oslo?
Oslo is one of Europe's key long-haul departure points.
FareEngine scans European departure airports in real time specifically because fares from gateway hubs frequently undercut the equivalent Heathrow price by hundreds of pounds. The positioning flight — a short hop in economy — costs a fraction of the saving, and for many UK travellers it adds no more than an hour to the overall door-to-door journey time.
