Compare Economy, Business & Award Flights in One Search
SubFlights shows when business class is worth the upgrade, when economy is overpriced, and when points offer better value than cash.
Powered by live airline and OTA data.

Why Comparing Flight
Prices Is Hard
Most flight search engines show economy and business class separately. That makes it difficult to understand:
- Whether business class is unusually cheap
- If economy is overpriced on a specific day
- How much business class normally costs on a route
- Whether upgrading actually offers good value
- When points are better than paying cash
The SubFlights Standard
SubFlights solves this by comparing everything side-by-side.
- Search both cabins simultaneously
- Instant price ratio analysis
- Historical value context
- Smart upgrade recommendations
