Error fare flights from Oslo, Norway to San Francisco, USA and return from Santa Ana, USA to London, UK for an incredible £180 with British Airways.
Appears to be a self-dump.
The actual itinerary ends in Gothenburg, Sweden, however because of the long overnight layover in London on the return journey, you can collect your bags and exit Heathrow airport if you wish (more info below).
Use Skyscanner to find cheap flights to Oslo if required.
There is almost a 24-hour layover in London on the return journey if you search 3 separate legs. For those of you living in the UK, you can simply ask for your bags to be sent to London when checking-in for your inbound flight in Santa Ana. Because of the very long layover, the check-in assistance will definitely grant your request. Then simply collect your bags, exit the airport and go home when you arrive at Heathrow.
Of course, never inform the airline that you do not plan on getting the London-Gothenburg flight.
WE STRONGLY RECOMMEND YOU WAIT FOR YOUR E-TICKET CONFIRMATION EMAIL BEFORE MAKING FURTHER PLANS.
BECAUSE THIS IS AN ERROR-FARE, THERE IS ALWAYS THE SMALL CHANCE THE AIRLINE MAY CANCEL THE TICKET.
