One of my visitors had been asking the travel time to Laoag City by land and here is my answer. 

There is no exact travel time by land from Manila to Laoag City. There is a big difference travelling by bus or by personal car/vehicle; or travelling during daytime or nighttime.

Travelling by bus or personal vehicle during daytime will take 10-12 hours depending on the traffic along the road. During nighttime, buses and personal vehicles could reach Laoag City in 7-8 hours.

By plane, Philippine Air Lines has a daily flight from Manila which takes 50 minutes to reach Laoag City.
