Web check-in saves a group a lot of queueing. Airlines typically open it 24 to 48 hours before departure for domestic flights.
Do it together
The coordinator can usually check in everyone on the same booking reference in one go on the airline's website or app. Do it as soon as it opens so seats are allocated close together.
Share boarding passes
Send each passenger their own boarding pass on their phone, and keep a combined PDF as backup.
Who still needs the counter
- Anyone checking in baggage (a bag-drop desk, usually quicker).
- Passengers needing wheelchair assistance or travelling with infants, on some airlines.
- International passengers, for document checks.
Quick answers
Can one person check in the whole group?
Usually yes, using the booking reference. Large groups may be split into several references.
