Thanks for quick responses.
Monica my aircraft condition is 92% & better. So that is not the reason.
Now to dmoose92. I did change my marketing. I had 2 permanent campaigns (newspapers & billboards)(continent of my base country) costing approx $70,000. I cancelled them & started 1 permanent campaign (television)(worldwide) costing $141,000.
I wonder if reducing from 2 campaigns to 1 campaign, even though I am spending double, could be the reason?
