A lot of misinformation flying around these airlines. First it was an off-duty pilot for Alaska Airlines in a jump seat. Then it was Horizon Airlines. Now this.
The media is generally unreliable.
Horizon’s a fully owned sub of Alaska. Just like Piedmont is a wholly owned sub of American.
Horizon is Alaska’s regional, short distance airline. Usually fly Dash 8’s. I doubt the SEA/SFO flight was Horizon.
