Answer:
The correct answer would be, The Canadian Airline would have used Lost Customer Recovery Strategy.
Step-by-step explanation:
When the sales of the Canadian Airline declines, they surveyed their target market which is Business Class Travelers. From the responses of the customers, they found out that customers feel bounded by the staff of the airplane. They think that they were totally controlled by the staff on board.
Now if the Canadian Airline would have surveyed their former customers, then they would have known why they left their airline, and what was their concerns and what they want in this airline; then the strategy used by them would have Lost Customer Recovery Strategy.
