British and US authorities have launched an investigation into possible price fixing for flights across the Atlantic. British Airways seems to be the main target of the probe, but American Airlines has received a subpoena, while United and Virgin both said they’re cooperating with authorities. These 4 airlines all fly from the US into London Heathrow. The investigation is looking into whether airlines colluded on fuel surcharges, which have now reached GBP35 ($65). If you’ve ever wondered how it happened that airlines were charging the exact same amount for fuel surcharges at the exact same time, this may help answer that question.
