Fix "Failed to fetch"

Done!

Real flights active

Step 1 of 5

Create a free Cloudflare account

Cloudflare provides a free service called Workers — small programs that run in the cloud and securely connect Plane Simple to flight data. No cost, no credit card needed.

1

Open cloudflare.com ↗ and click "Sign up"

2

Enter email and password, then verify your email from the confirmation link they send

3

When asked about a domain, click "Skip" — you don't need one

💡 You're now on your Cloudflare Dashboard. Leave this tab open for Step 2.

Step 2 of 5

Deploy the Cloudflare Worker

1

In Cloudflare Dashboard: Workers & Pages → Create → Create Worker

2

Name it plane-simple-proxy, click Deploy, then Edit code

3

Select all (Ctrl+A), delete, paste the contents of plane-simple-worker.js, click Deploy

4

Copy your Worker URL at the top — it ends in .workers.dev

💡 The "Missing headers..." error in the Cloudflare preview is normal — it means the Worker deployed correctly.

Step 3 of 5

Get your Duffel API key

1

Open app.duffel.com/join ↗ and create a free account

2

Go to Developers → API keys in the left sidebar

3

Copy the Test key (starts with duffel_test_)

💡 The test key shows real flight data but won't process any payments — safe for exploring.

Step 4 of 5 (optional)

Get your Google Places key

1

Open console.cloud.google.com ↗ and sign in

2

Create a project, enable Maps JavaScript API and Places API

3

Go to Credentials → Create Credentials → API key and copy it

4

Restrict it to your *.pages.dev domain under Website restrictions

⚠️ Google gives $200 free credit/month — more than enough for personal use.

Step 5 of 5

Add your keys to Settings

1

Click Settings in the left sidebar

2

Paste your Worker URL, Duffel key, and optionally your Google key

3

Click Save Keys — the connection test runs automatically

4

Look for 🎉 "Everything working!" — that means you're live

💡 Getting "Failed to fetch"? You need to host the app online. See Step 5b.

Step 5b — Hosting

Host on Cloudflare Pages (free)

Opening the HTML file directly from your computer blocks external connections (browser security). Hosting it on Cloudflare Pages fixes this permanently using the same free account you already have.

1

Cloudflare Dashboard → Workers & Pages → Pages tab → Create → Upload assets

2

Name your project (e.g. plane-simple), click Create project

3

Download the plane-simple-deploy.zip file and drag it (the ZIP, not the HTML) into the upload box

4

Click Save and deploy. In ~30 seconds you'll get a .pages.dev URL — bookmark it

5

Open that URL, re-enter your keys in Settings, click Save → Test Connection

💡 When you get a new version of the app, go to your Pages project → "Create new deployment" → upload the new ZIP. Same URL.

🎉

You're live!
