CanJet Airlines Simplifies Military VFR Fares!
Canada's Military has the best men and women dedicated to our freedom and security. CanJet Airlines salutes our Canadian Military personnel and we sincerely thank them for a job well done! We also extend our heartfelt gratitude to military spouses and partners because we know that, without you, your spouses and partners wouldn't be able to perform the exceptional jobs they do every day. We tip our hats to all of you and, to show our appreciation, CanJet is pleased to offer Canadian military personnel on active duty, as well as their dependents, 10% off our everyday low fares for leisure travel only. Military members and their dependents must state the military member's ID number when booking and the military member must present ID upon check-in.
To check our schedule, go to Flight Schedules. At this time, these fares cannot be booked on the Internet. You must book by calling our Reservation Centre at 1-800-809-7777 or by contacting your travel agent.
