JO -
Good arguments, but not really accurate.
Sunwing has not suddenly expanded by 50%. If you go back and look at the past 5 years of the tour company, you will see a massive list of other operator's chartered to fly for Sunwing.
This includes JetsGo, Flair, Kelowna Flightcraft, North American Airlines, Excel, Zoom, and the list goes on. In fact, even in the last year Sunwing has used Zoom, Flair, and AeroMexico.
All they are doing is utilizing their own airplanes on well-established routes. The amount of wet-leasing this year is dramatically lower than in years past, which is much more cost-effective than paying through the teeth to another airline.
In fact, what they are doing is lowering their costs as I see it.
Yes, they have expanded. However, looking at the fact that they will have 15 airplanes this year as opposed to 7 or whatever it was before is not the whole story.
Just my $.02.
