FlightByte vs aviationstack

Two different products that share a search result. aviationstack sells requests against a large catalogue of aviation data. FlightByte sells watched flights and tells you the moment one changes. If your job is to react to a specific flight, the difference is the whole product.

aviationstack pricing, free tier and API key

What each plan costs, what the free plan allows, and how a key is issued, from aviationstack’s own pages on October 15, 2026. Every plan buys the same thing, requests, so the plan you need depends on how often your code asks.

EnterpriseCustomCustom

Platinum support is an add-on from $479.88 a year. Since July 2026 aviationstack is part of the APILayer suite, and apilayer.com sells the same plans under other names: Starter, Professional and Enterprise. E-mail warnings go out at 75, 90 and 100 percent of the quota.

aviationstack free tier

Free is 100 requests a month, for non-commercial use, with no support. It leaves out history, routes, autocomplete, schedules and future flights, and it asks for no credit card.

At one request every five minutes for the last six hours of a flight, 100 requests watch about one flight a month.

aviationstack API key: how to get one

  1. Sign up at aviationstack.com with a name, e-mail address and password; the Free plan asks for no card.
  2. Copy the access key from your account.
  3. Send it as the access_key query parameter to api.aviationstack.com/v1.

One APILayer account and key now covers aviationstack and the other APILayer APIs; older aviationstack keys keep working.

When aviationstack is the better choice

It is a broader product, and for three jobs it is the right one.

You need the catalogue

Lists of airports, airlines, aircraft types, routes and cities from one API. FlightByte only carries the airport data that belongs to a flight.

You need history

Three months of past flights on paid plans. FlightByte keeps a live window, and a delivery log for the flights it watched, nothing older.

You need positions

Latitude, altitude and speed for airborne flights. FlightByte tells you a flight is en route; it does not tell you where.

When FlightByte is

When there is a particular flight you care about, and something in your product has to happen when it changes.

You would otherwise poll

A status endpoint answers the easy question. Knowing how often to ask, what changed, and what to do at three in the morning is the work; FlightByte does it and sends the result.

You count in flights, not requests

A booking is a flight. Pricing per watched flight means the bill tracks your business, not how nervous your poller is.

You need to prove what was sent

Every delivery is signed and logged with its HTTP status and latency. When a driver says the message never came, you can look.

What watching 500 flights a month costs

Assume a modest poller: one status request every five minutes for the last six hours before each flight, which is 72 requests per flight and still misses a gate change by up to five minutes.

nothing; the polling is inside the price

FlightByte polls each flight on its own schedule, roughly 40 to 120 upstream requests per flight, tighter at the gate than a five-minute loop and looser a day out. That cost is inside the plan. See pricing.

Moving over

Most integrations map in an afternoon. The shapes are similar; the difference is that FlightByte splits gate and runway times, gives every time a UTC and a local form, and adds a phase you can branch on.

What you stop writing. The polling loop and its schedule, the table of last-seen values, the diff, the retry queue for your own notifications, and the log that says what went out. A subscription replaces all of it:

Questions people ask before switching

How much does aviationstack cost?
Basic is $49.99 a month for 10,000 requests, Professional $149.99 for 50,000 and Business $499.99 for 250,000, about 10 to 15 percent less billed yearly; Enterprise is custom. Requests over the quota cost about $0.02 down to $0.008 each, by plan. FlightByte is $9, $19, $49 or $99 a month, counted in watched flights rather than requests.
What are the aviationstack free plan limits?
100 requests a month, for non-commercial use, with no support, and without history, routes, autocomplete, schedules or future flights. No credit card is asked for. At one request every five minutes for the last six hours of a flight, 100 requests watch about one flight.
How do I get an aviationstack API key?
Sign up at aviationstack.com with a name, e-mail address and password; the Free plan asks for no card. Your access key is in your account, and it goes in the access_key query parameter. Since July 2026 aviationstack is part of the APILayer suite, so one APILayer account and key can cover it.
Can I use both?
Yes, and some teams should. aviationstack for reference data and history, FlightByte for the flights you need to be told about. The two do not overlap much.
Does FlightByte have live aircraft positions?
No. FlightByte reports status, times, gates, terminals, baggage carousels, aircraft and codeshares, and tells you when any of them change. It does not carry ADS-B positions or tracks.
Does FlightByte have a free plan?
Yes. Free watches 3 flights a month with 120 lookups, every event type and signed deliveries, and commercial use is allowed. Past that, Hobby is $9 a month for 100 watched flights and 4,000 lookups, and extra flights on paid plans are billed rather than refused.
