Interesting 
Judging from the flight number, it’s a ferryflight. That significantly improve the range…
Yeah, must be a ferry.
Could be a ferry, too…
It’s a ferry. Sun Country use some Transavia aircraft in the winter season, and this one is heading back home.
Insane but definitely a ferry

Here is a flight that’s pushing the 738 limits…Could go another 2,000 if needed.
What is that plane moving?
It’s a new aircraft that was picked up at the factory. They have taken delivery of 4 new 737-800’s in the last several months, as seen by the other three flights on the “SAS9145” link.
