Enter any route and see what the trip really costs — points, taxes, and your net cash after every card credit is applied.
Stop leaving points on the table.
AeroStack connects all your travel rewards cards — Chase, Amex, Capital One, Citi, Bilt — and shows you exactly what your points are worth, what credits are expiring, and how to book award flights for free.
THE NET COST ENGINE
AeroStack is the only app that calculates your TRUE net cost after every card credit, travel credit, and fee waiver is applied. $500 in unused credits → Net cash cost: $0.
AWARD FLIGHT SEARCH
Search award availability across 26 mileage programs. See Business and First class seats, transfer partners, and book directly with your points.
CARD BENEFITS TRACKER
Never miss an expiring credit again. AeroStack tracks your Amex Platinum ($1,540 value), Chase Sapphire Reserve ($1,050 value), and 44+ more cards automatically — now with a Credits Hub that puts every credit in one place.
AI TRAVEL CONCIERGE
Ask anything. "Which card for dining in Tokyo?" "What's my best redemption right now?" Powered by Claude AI.
LOUNGE ACCESS FINDER
See every airport lounge you can access with your current cards — before you get to the airport.
PRICE DROP ALERTS

Developer Response
That's the whole mission — your cards are already paying for benefits, AeroStack just makes sure you actually use them. Thank you for the kind words and welcome to the community! 🛫

TRUE NET COST FOR ANY ROUTE
Enter where you want to go and see what the trip actually costs you — points needed, real taxes, and your net cash after every card credit is applied. Economy through First, side by side, with the transfer path to book it.
CREDITS THAT RESET WHEN THEY SHOULD
Your credits now come back on their real schedule — monthly, quarterly, twice a year, or on your card anniversary. Monthly credits show what you get each month, so a $300 annual credit reads as about $25 a month.
MORE ACCURATE NUMBERS
Card credits now apply only to the card you actually pay with, and savings are capped at what the trip really costs. Award taxes and fees display correctly. The points calculator values each program's own balance instead of your whole portfolio.
Some savings figures are smaller than before. They are also correct.
