Now for a little spin: If only 1 of every 100 passengers boarding an Alaska flight opted for an IFE unit, they would need over 13,000 units to meet demand. If you allow for multi-stopover flights by a single aircraft with, say, 4 flights per day, you would still need over 3,200 units to meet that 1% demand. Land a couple of the top 5 carriers and you can up that number to 30,000 units. Then raise the demand level to 10% of passengers and you're talking 300,000 units. Will it happen? Can't say. Could it happen? Definitely.
