Can I use AI on a plane with no Wi-Fi?

Quick answer

Yes, if the AI runs on your laptop. ChatGPT, Copilot and Gemini need an internet connection, so they stop working without in-flight Wi-Fi. An offline AI app downloads a model to your laptop once, before you travel, and then drafts, summarises and answers questions about your files in airplane mode. Download the model at home, test it with airplane mode on, copy the files you need onto the laptop, and charge up.

It is one of the best places to get work done: no meetings, no messages, a few uninterrupted hours. The catch is that most AI tools go quiet the moment the doors close. The fix is simple, but you have to do it before you leave home.

Why ChatGPT stops working in the air

ChatGPT, Copilot and Gemini do their thinking on servers far away. Your laptop sends your question over the internet and waits for the reply. In airplane mode, or on a flight without Wi-Fi, nothing gets through. Even with paid in-flight Wi-Fi, connections can be slow and drop out.

An offline AI app works differently. It downloads an AI model to your laptop once. After that, every answer is worked out on your own computer, so it does not matter whether you are over the Atlantic or in a tunnel. The trade-off is that a laptop runs a smaller model, which is great for writing and your own documents but weaker on general facts.

Before you fly

  1. Install and download at home. The model is the big part: about 2.5 GB for a small model and 5.0 GB for a mid-sized one. Allow time on a good connection.
  2. Test in airplane mode. Turn on airplane mode, open the app and ask a question. If it answers, you are ready.
  3. Put your files on the laptop. Documents that live only in OneDrive, Google Drive or iCloud may not open offline. Make sure they are downloaded to the laptop.
  4. Charge everything. Pack the charger and check if your seat has power.

On board

  • Follow the crew's instructions about when laptops can be used.
  • Keep the laptop in airplane mode. Offline AI does not need any connection.
  • Start with the job that matters most, while the battery is full.
  • Emails you draft can wait in your outbox and send when you land.

Battery and speed

While it is writing an answer, the AI keeps your processor busy, a bit like exporting a video. Between answers it uses very little. In practice, a handful of drafts and summaries barely dents the battery, while summarising a long report several times over will. Laptops with Apple Silicon handle this especially well. On many Windows laptops, the processor slows down on battery, so answers take a little longer than at your desk.

Good jobs for a flight

  • Draft replies to the emails you downloaded before take-off.
  • Summarise a long report or board pack and pull out the actions.
  • Ask questions of a contract or proposal: "What are the payment terms?"
  • Proofread a presentation or turn notes into a tidy first draft.
  • Shrink big attachments so they send on the hotel Wi-Fi. See how to compress a PDF without internet.

How WorkOffline handles this

WorkOffline is made for exactly this. Set it up once on Wi-Fi (it picks and downloads a model sized for your laptop), then chat with your files, draft, proofread and compress attachments in airplane mode. A Battery saver setting uses fewer processor cores and shorter answers to stretch a charge. Offline lock blocks every connection if you want to be certain nothing goes online. WorkOffline runs on Mac and Windows; iPhone and Android are planned.

Frequently asked questions

Does ChatGPT work on a plane without Wi-Fi?

No. ChatGPT runs on servers, so it needs a connection. With paid in-flight Wi-Fi it may work, but speed and reliability vary.

Can I download the AI model at the airport?

You can try, but models are large: about 2.5 GB for a small one and 5.0 GB for a mid-sized one. Airport Wi-Fi is often slow or time-limited, so do it at home.

Is it allowed to use a laptop in airplane mode?

Airlines generally allow laptops in airplane mode during the flight, with limits during taxi, take-off and landing. Always follow the crew and your airline's rules.

Will offline AI drain my battery on a flight?

It uses more power than typing because the processor works hard while each answer is written. Short tasks are fine. For long summaries, plug in if your seat has power.

Can I use offline AI on my phone on a plane?

Some phone apps run small models on the device. WorkOffline is for Mac and Windows today, with iPhone and Android planned.
