Google Flights (Cash Prices)
Search for flight prices and schedules. Essential for comparing: "Is 88,000 United miles better than paying $900 cash through the Chase portal?" (Chase portal pricing is now dynamic via Points Boost, ~1.5-2.0 cpp on select bookings; verify the actual quote.)

Portal Comparison Math
Chase Sapphire Reserve: dynamic Points Boost pricing, typically 1.5-2.0 cpp on select bookings (not a fixed floor). Verify actual portal price for the specific booking. If cash price is $900, portal cost = 60,000 UR points. If award price is 88,000 United miles, cash via portal is better value.
Amex: typically 1 cpp via portal (worse value, use transfers instead).
Capital One Venture X: 1 cpp via portal, but transfer partners can be better.

Workflow: Compare Award vs Cash
- Search cash prices on Google Flights via SerpAPI
- Estimate portal cost. Chase uses dynamic "Points Boost" pricing (~1.5-2.0cpp on select bookings, not a flat rate). Amex/Capital One ~1.0cpp. For rough math, run the actual portal quote against the cash price; do not assume a flat cpp on Chase.
- Compare with award price from Seats.aero
- Lower number wins (accounting for the value you place on each currency)
Notes
- Cached results are free (1hr cache). Set
no_cache=trueto force fresh. deep_search=truegives browser-identical results but is slower.- Results include
price_insightswith historical price data and trend. - Multi-city supports open jaw itineraries natively.
- Hotels support vacation rentals mode for Airbnb-style results.
