Flight delay

My husband got the sad news of his grandfather being on his deathbed, and booked his flight immediately to see him for last time. Flight original departure time was 22h00, however after 5delay emails, the flight was postponed by 4hours!!!! He tried getting another flight, but could not. This is really terrible service. Not what you would want in such a sad time. We have had numorous kulula flights cancelled/ delayed. (We almost missed a wedding and on another time a 90th birthday party becausr of delayed flights) you cannot rely on Kululas service or flights being on time. This is really bad service! I am planning to take our business to another company.
