Here are the top websites and tools people use to search for and book award flights with miles — grouped by type (airline program sites, award-search/aggregator tools, and paid concierge/booking services). I’ve noted each service’s main strength and when to use it.

Airline loyalty-program sites (best for booking directly with that program)

• United MileagePlus (United.com) — Great for searching and booking United-operated and many Star Alliance award seats; reliable for booking online. (millionmilesecrets.com)
• Delta SkyMiles (Delta.com) — Widely used for Delta inventory (note: dynamic pricing and partner availability vary). (millionmilesecrets.com)
• American AAdvantage (aa.com) — Essential for searching American and some partner awards (some partner space won’t show; you may need partner sites). (millionmilesecrets.com)
• Alaska Mileage Plan (alaskaair.com) — Excellent partner award access (often shows awards that aren’t on partner sites). (millionmilesecrets.com)
• British Airways Avios (ba.com) — Very useful as a search tool to find some partner awards (e.g., on oneworld/other partners) even if you intend to book with another program. (millionmilesecrets.com)

Award-search & aggregator tools (best for cross-program searching and finding hard-to-find space)

• Point.Me (Point.Me, formerly Juicy Miles) — Powerful multi‑airline award search that shows which programs can book an itinerary and how to do it; offers detailed results and transfer-path guidance. Good first stop for international itineraries. (Point.Me)
• Seats.aero — Strong real-time award-search engine that digs into partner inventory and provides flexible search filters and alerts. Useful when you need more granular partner coverage. (milesopedia.com)
• AwardFares — Aggregates award availability across programs, offers timeline/visual tools and alerts to monitor award space over many dates. (en.wikipedia.org)
• PointsYeah / PointsYeah Daydream Explorer — Good for broad/flexible searches (anywhere tools and calendar/map views) to see where your points will get you. (carryonbetter.com)

Tools for tracking balances, alerts, or managing award searches

• AwardWallet — Track multiple program balances and set availability alerts (helpful to know when to act). (awardwallet.com)

Paid concierge / booking services (when itineraries are complex or you want an expert to book)

• Point.Me concierge — Paid service to research and book complicated multi-carrier international award itineraries; useful if you don’t want to do transfers/phone booking yourself. (Point.Me)
• Specialist award brokers / agents (e.g., independent award brokers and sites like AwardFares’ paid services) — They’ll book complex partner routings for a fee when the DIY route is too hard. (en.wikipedia.org)

Quick tips on how to use them effectively

• Start with airline program sites when you plan to redeem that program’s miles (they’re the source of truth for what you can actually book). (millionmilesecrets.com)
• Use aggregators (Point.Me, Seats.aero, AwardFares) to find options across many programs and to discover which program can book the itinerary. (Point.Me)
• If you find partner space but can’t book it online with your miles, try calling your loyalty program or use a paid concierge/award broker. (millionmilesecrets.com)
• Set alerts (AwardWallet, Seats.aero, AwardFares) for routes/cabins you want — award space changes quickly. (awardwallet.com)

If you want, I can:

• Recommend the best two or three of these specifically for your frequent‑flyer programs (tell me which programs you hold), or
• Run a quick comparison of features/pricing for 2–3 of these tools (e.g., Point.Me vs Seats.aero vs AwardFares).
