Short answer: Airline phone lines mean a long menu and then a long hold. OsmO can take that call for you from your AI app. You tell it the booking reference, what happened and what you want, and it waits in the queue, makes the request when an agent picks up, and reports back what the airline offered.
Give the booking reference, the flight and the outcome you want, plus what you would accept instead.
Long holds cost the same as short calls: 3 credits per answered call.
Keep card numbers out of the request. If the airline wants a payment, you finish that part yourself.
Toll-free numbers, like most airline helplines, are among the numbers OsmO can call from an AI app.

The full guide
Calls worth handing over
- A cancelled or badly delayed flight that needs rebooking.
- Asking for a refund instead of a travel credit, where your fare allows it.
- Chasing a delayed bag, or checking a claim reference.
- Asking whether a seat, a bag or a special request has been added to the booking.
What to give your AI
- Name the airline. Your AI app or OsmO looks up its customer service line.
- Give the booking reference and the last name on the booking.
- Say what you want first, then your acceptable alternatives (another flight, a different airport, a refund).
- Say what it must not accept, for example "no overnight connections".
Know your rights before the call
In the US, the Department of Transportation says you are owed a refund when an airline cancels or significantly changes a flight and you choose not to travel. The UK and EU have their own delay and cancellation rules. Knowing the rule helps you write the request: "I am asking for the refund I am owed under the DOT rule" is a stronger request than "see what they can do".
OsmO reports what the airline said. It is not legal advice, and an agent's promise on the phone is worth checking against the email or app afterwards.
What it costs
An answered call uses 3 credits however long it lasts, and a call nobody answers is free. The 50 credits you get on sign-up cover about 16 answered calls.
Questions people ask
What if the airline needs to speak to me?
Some airlines insist on talking to the passenger for certain changes. OsmO tells you when that happens, with the reference and what is left to do.
Does it cost more if I am kept on hold for a long time?
No. An answered call uses 3 credits whatever its length, so a long hold costs the same as a short call.
Which countries does it work in?
You can sign in with a mobile number from the United States, Canada, the United Kingdom or Australia (India too). Calls are placed from the OsmO number for your country.
