I live in WPG. I am a flight attendant I have to fly to and from Winnipeg to Calgary for work not reimbursed for my flight expenses. Can I deduct this travel expense?

If your employer is based out of Calgary, CRA would consider you to be just "travelling to/from work" and no deduction would be allowed. 

From the CRA, here are the rules for claiming Traveling Expenses as an "employment expense".

Travelling expenses include food, beverage, lodging and transportation (such as airplane , train, bus, etc) expenses but not motor vehicle expenses. You can deduct travelling expenses as long as you meet all of the following conditions:

• You were normally required to work away from your employer's place of business or in different places.
• Under your contract of employment, you had to pay your own travelling expenses.
• You did not receive a non-taxable allowance for travelling expenses. Generally, an allowance is non-taxable as long as it is a reasonable amount.
• You keep with your records a copy of Form T2200, Declaration of Conditions of Employment, which has been completed and signed by your employer.
