# SerpApi key - per-platform flight prices (what MakeMyTrip, Goibibo, EaseMyTrip
# and the airline each charge for the SAME seat, plus a booking link for each).
# Without it the app falls back to comparing every channel at one fare, which is
# the old behaviour: honest, but it can only rank on offers, not on price.
# Free tier is 250 searches a month. Budget 2 calls per user journey: one search,
# one seller lookup for the itinerary they pick.
