Check in for a flight the moment it opens

What you can get

Reaches your accounts Creates or changes things in accounts you connect, with your approval.

1. It does

   • Reads the flight confirmation in your email
   • Checks you in on the airline's site or app when the window opens
   • Sends you boarding passes and flight status updates; does not pay for extras without approval

2. It stops and asks

   • Before the window: confirm flight, travellers and what may not be paid for.
   • When it opens: check that boarding passes arrived, and do it yourself if not.
   • On the day: treat status updates as a prompt to check the airline's own app.

3. You approve

   • No authority to buy seats, bags or upgrades without asking
   • Your approval before any change to the booking

The source case

On X, @MichaelLevin lists what Instinct did in about a week, including checking the author and their fiancée in for a flight right when the window opened, tracking a late inbound plane and sending a notice when boarding started. The post does not name the airline or say how the boarding passes were delivered. @ShanuMathew93 reports the other side: a post on 2026-09-09 says it failed miserably at checking into a flight, and a post three days later says it checked the author in to a flight proactively. The two posts do not say whether they concern the same flight. @thisiskp_ says it dug a flight confirmation out of their inbox and watches it for schedule changes and check-in windows. Separately, @adambn reports emails and events queued for up to 3-5 hours on a bad day. All checked on 2026-09-24; individual reports, not evidence of what will happen for the reader. @aaronqfu reports Instinct checking them in but submitting APIS data with a first name demoted to a middle name, which did not match their passport and led to CBP secondary screening before it was cleared up; @manosaie reports being checked in from a beach in France with boarding passes sent and a checked bag paid for, with no issue described. @marketing.withalex says on TikTok that Instinct checked him into a flight from a voice note; this does not show the airline, the timing or a boarding pass. @Praval says on X that his agents across Instinct and two other tools checked him in on a preferred seat on an Air India flight, but the post does not say which of those agents did the check-in, when it happened relative to the window opening, or whether boarding passes arrived. @alecwilcock says on X that they booked flights entirely through Instinct, asked it to check them in, and on the way to the airport asked it which gate the flight was likely to leave from and found the guess was right, but the post does not name the airline, say when check-in happened relative to the window opening, or say how boarding passes were delivered.

How to try it

Editorial, not from the source

1. Point it to the flight confirmation, or let it find it in your email, and confirm the flight number, date and travellers.
2. Add what check-in may ask for: passport details, loyalty numbers, and what to do if seats need choosing.
3. Say what it must not do: pay for seats, bags or upgrades without asking.
4. Set your own reminder for when the window opens, so you can check in yourself if nothing has arrived.
5. When the boarding passes come through, open them and check names, flight and seats.

Open Instinct to try it. That is the product's own site; this guide is not part of it.

Limits and confirmation points

• Six users, mixed results. Three report check-ins done, one of them with a name error in the border data; another reports a failure and, days later, a success. None of the posts names the airline.
• Messages can be late. One user reports emails and events queued for up to 3-5 hours, which would matter for a timed window.
• Some airlines require document checks, extra questions or check-in at the airport. An agent may not be able to finish those.
• Seat changes, bags and upgrades can cost money. One user reports it paid for a checked bag during check-in, and the post does not say whether they approved it. Nothing here authorizes paying for them.
• One user says Instinct checked them in but, they guess, demoted a first name to a middle name in the APIS data. It did not match their passport, and border control questioned them on landing (CBP secondary screening) before it was cleared up. Check traveller names before check-in is submitted.

The window opened and nothing has arrived

Check in yourself. One user reports a failed attempt, and another reports messages delayed by hours; your own reminder is the backstop.

Check-in asks for passport or visa details

Supply them yourself, or finish check-in at the airline's site. Document checks may need you.

An update says the inbound plane is late

Confirm on the airline's app before changing plans. One report describes the late plane being tracked; the airline is the authority.

Automated check-in submits a name field (e.g., APIS/border data) that doesn't match your passport exactly

Review the name and document fields the agent submits during check-in before an international flight, and correct any field that reorders or demotes a name part.
