外國遊客在8號風球期間可以乘搭的士去機場嗎？大概要多少錢？

Yes, taxis generally operate during Typhoon Signal No. 8, but with a surcharge of HK$50-100 per trip. From Central to Hong Kong International Airport, the normal fare is about HK$300-400, plus the surcharge, so expect to pay around HK$400-500. Availability is limited, so book via apps like HKTaxi or Uber, and allow extra time (at least 1.5 hours) for the journey. Confirm the surcharge with the driver before boarding. If the taxi is unavailable, consider hotel shuttles or the Airport Express if still running.
