Neither. I want to have a booking engine that compares prices from multiple sites (all of which have an affiliate program). So when someone books clicks on a link to book a flight on my site, I earn commission from whatever site they booked the flight from.
Same as the booking engine that cheapflights.com and skyscanner.com have.
