Oil prices decreased on Monday as ongoing omicron variant has forced many airlines to halt their flights in the US disrupting travel during the busy holiday weekend.
International benchmark Brent crude was trading at $75.54 per barrel at 0641 GMT for a 0.32% decrease after closing the previous session at $75.79 a barrel.
American benchmark West Texas Intermediate (WTI) was at $72.81 per barrel at the same time for a 1.32% loss after trade ended at $73.79 a barrel in the previous session.
Despite a relatively better trading last week with both benchmarks posted by around 4% increase as omicron variant of COVID-19 appears to be a milder disease, concerns over its contagion remained.
Airlines in the US canceled nearly 1,000 flights on Sunday as the omicron variant of COVID-19 spread quickly, increasing the number of sick calls from pilots.

The spread of omicron among employees caused the cancellations, according to United Airlines, Delta Air Lines, American Airlines, and JetBlue Airways.
