The spread of the Covid omicron variant across the world could further delay the travel industry's recovery, a fresh challenge just as international trips were on the upswing after a 20-month slump.

The variant, first reported by South African scientists last week with the first U.S. case confirmed in California on Wednesday, has sparked a new host of travel restrictions that took many travelers by surprise, leaving some stranded as several countries temporarily barred flights or arriving passengers from the region.
