In response to the recent volcanic activity in Hawaii, Air Canada has extended its policy for customers who purchased an Air Canada ticket no later than May 16, 2018 for travel to or from Kona or Hilo between May 16 and May 31, 2018.
If you are scheduled to travel on the above dates, you may contact Air Canada Reservations (1-888-247-2262) to change your flight, free of charge, to another date between now and June 15, 2018, subject to availability in the cabin you originally purchased. Otherwise, any fare difference will apply.
You may also choose to travel to an alternate destination. Any change fees will be waived, provided you are travelling between now and June 15, 2018. However, any fare difference will apply.
If you purchased your ticket with Aeroplan, or Air Canada Vacations, please contact them directly.
