Flight check-in reminder on WhatsApp
Updated .
A flight check-in reminder on WhatsApp is a message just after online check-in opens, and another when it's time to leave. With Mindie, send "remind me on 14 December at 9:05am to check in for my flight to Denver" and it arrives right on time.
Checking in late usually means the middle seat at the back. On a busy trip, it's also one more thing to remember while packing.

Packing list
When to be reminded
- A few minutes after check-in opens, often 24 hours before departure.
- When to leave for the airport, with time for traffic and security.
- The night before, to check the packing list.
Why it slips
- Check-in opens at an awkward time, like the middle of a work meeting.
- The airline email gets buried under everything else.
- Travel days are busy, and it's easy to assume it can wait.
Habits that help
- Set the reminders when you book. The departure time is right there.
- Keep a packing list in Mindie and add to it in the days before.
- Screenshot the boarding pass once you have it, in case the app won't load at the gate.
How Mindie handles it
Send the check-in time and the leave time as two messages, or one with both. Mindie confirms and messages you at each, in your timezone. If you're travelling across time zones, say which one you mean. Reply "done" once checked in.
What Mindie doesn't do
- It doesn't check you in, book flights or track flight status.
- It doesn't connect to airline apps.
- It doesn't message anyone else. Reminders come to your own chat only.
