SINGAPORE, Jan 11 (Reuters) - Asia"s cash differentials for jet fuel rose to their highest premiums in three weeks on Tuesday, while the prompt-month spread for the aviation fuel in Singapore widened its backwardated structure. Cash premiums for jet fuel jumped to 57 cents per barrel to Singapore quotes, the highest since Dec. 21, while the Jan/Feb time spread traded at 51 cents per barrel on Tuesday. The jet fuel market, however, is expected to remain under pressure in the near term as surging Omicron cases around the world continue to dampen aviation demand, trade sources said. Global scheduled flight seats have dropped 7.2% in the week to Monday, compared with the week before, while airlines have removed 8.7 million seats from their overall January capacity in the last week, according to aviation data firm OAG. An additional 8.3 million seats were also removed from the February-March schedule, OAG said. China"s flight capacity inched up 1.5% in the week to Monday, but seat capacity in India and Japan this week were down 6% and 4%, respectively, OAG data showed. "While the impacts from Omicron remain far from certain, what is clear so far is that domestic and international air travel booking have taken a hit in December setting the stage for continued weakness in air travel for Q1 2022," Fitch Solutions said in a note. Emerging data pointing to less severity and hospitalisation rates, however, would likely open the door to renewed air travel in the coming quarters, analysts at Fitch added. Refining margins or cracks for jet fuel dipped 8 cents to $12.55 per barrel over Dubai crude during Asian trade on Tuesday.
