Been looking for five first class tickets around the end of March for PDX-FAI
For the exact same itinerary, Alaska app showing ~$1k per passenger and Alaska website(and google flight) showing ~$550 per passenger.
I tried searching for just one ticket, and the price is the same for one ticket, but for five there is a huge difference.
I suspect the app and website using different demand-price calculation. Just want people be aware of this.
