Industry data show business travellers are taking longer trips than before COVID-19, leaving airlines adjusting flight plans. Qantas Airways Ltd (QAN.AX) and Virgin Australia say higher airfares have so far offset any revenue impact from fewer business trips. Ajit Chouhan, a Texas-based human resources executive, used to go on one-day business trips to San Francisco at least once a month before the pandemic. "If I'm on a business trip, do I want to stay an extra day if my partner's at home?" One-day journeys accounted for around 4% of domestic business trips globally in 2019, according to CWT data, versus 3% now.
