FOR TRAVELERS WITH COMPLEX STACKS

Your travel stack, optimized for the trip ahead.

TravelStack turns your cards, status, certs, points, flights, and hotels into a time-sequenced action plan. We surface what you'd miss — credits to use, upgrades to request, deadlines to beat, hotels to email — and write the messages for you.

SubjectUpcoming stay — Diamond + FHR confirmation, 23–26 May

Hello,

I'm writing to confirm benefit details for our upcoming stay, 23–26 May (reservation #HHTK-4429187). The booking was made through American Express Fine Hotels & Resorts; both travelers are Hilton Honors Diamond.

Could you confirm that the FHR $200 property credit, daily breakfast for two, 4pm late checkout, and Diamond upgrade priority are applied to this reservation? If a high-floor king with city view is available, we'd love to be considered for the upgrade.

Many thanks,
Michael & Nico

How it works

Three steps. About 10 minutes for your first trip.

STEP 01

Add your trip

Paste an itinerary, forward a confirmation, or describe your trip in a sentence. We extract flights, hotels, dates, travelers, and constraints into structured objects you can confirm.

'TOKYO + KYOTO, MAY 23–JUN 6, TWO OF US, CONRAD + PARK HYATT, HAWAIIAN SFO–HNL–KIX'
STEP 02

Add your stack

Cards, airline and hotel status, certificates, free nights, expiring credits, preferences. One-time setup, then we use it for every trip.

Ranked actions with deadlines, dollar values, source citations, and pre-written messages. Email reminders so you don't have to remember.

Where TravelStack fits in your stack

We don't compete with the tools you already use. We sit on top of them.

BUILT ON VERIFIED DATA

Every recommendation cites its source.

Benefit data is verified directly from issuers, airlines, and hotel programs. Each canonical record has a source URL, a last-verified date, and a confidence level. Stale data is flagged automatically. We tell you what we know and how we know it.

Pricing

Three ways in. The free tier earns its keep on its own.

WHO MADE THIS

Built solo by an obsessive traveler.

TravelStack started as a spreadsheet for my own trips. Then a longer spreadsheet. Then a folder of email drafts. I'm a product manager who's been obsessive about award charts, credit card credits, and stacking benefits since 2014. The tools that exist optimize wallets, search hotels, or store itineraries — none of them tell you what to do for the trip you're actually taking. So I'm building it.
