Uber and Lyft both operate throughout Waikiki and most of urban O'ahu, plus a local competitor, Holoholo, that often undercuts on price. Typical fares from Waikiki run $25 to $40 to Honolulu Airport (HNL), $8 to $14 to Ala Moana Center, $12 to $18 to downtown or Chinatown, and $60 to $90 each way to the North Shore. Both apps surge in early evenings, on weekends, and after major events at the Hawaii Convention Center or Aloha Stadium. At HNL, designated rideshare pickup is on the second median of the departures level (across from Lobby 2 for international/interisland Terminal 1, Lobby 8 for mainland Terminal 2). Comparing both apps before booking can save $5 to $15 per ride; you can also lock in airport-pickup pricing in advance through Uber Reserve.
"Check both apps every time, prices vary by $10 or more depending on surge. From the airport to Waikiki we paid $28 on Lyft when Uber was quoting $42, both arrived in under five minutes."
