# What happens if you don't check in online for a flight?

> Usually nothing bad: you check in at the airport kiosk or desk instead. Skip check-in entirely and you can't board; some low-cost airlines charge a fee.

On most airlines, nothing serious happens: online check-in is optional, and you can check in at the airport counter or a self-service kiosk instead. The main downsides are lines, fewer seats to choose from and, on some low-cost airlines such as Ryanair, a fee for checking in at the airport. What you can't do is skip check-in altogether: if you don't check in before the deadline, you can't board and are usually treated as a no-show.

## What changes if you skip online check-in

- **You check in at the airport.** At a kiosk or desk, with your passport or ID and booking reference.
- **You must make the cutoff.** Airport check-in and bag drop close before departure, often 45–60 minutes ahead and earlier for international flights. Arriving late can mean being refused boarding.
- **Seat choice is narrower.** By the time you reach the counter, the best free seats may be gone.
- **Possible fees.** Some ultra-low-cost carriers charge to issue a boarding pass at the airport.
- **On overbooked flights,** passengers who check in last are more likely to be bumped.

## Why online check-in helps

1. You choose from all free seats as soon as check-in opens, usually 24 hours before departure.
2. You get a boarding pass on your phone and can go straight to security if you have no checked bags.
3. You confirm you're traveling, which helps the airline plan.

## When you still need the counter

Even after checking in online, you must visit a desk or bag drop if you are checking luggage, and on some international flights the airline needs to see your passport and visa before you board.

## FAQ

**Why can't I check in online for my flight?**
Common reasons: check-in isn't open yet, the airline needs to verify your passport or visa for an international trip, the ticket was booked through another airline or agency, or the booking includes a lap infant or special assistance. In those cases, check in at the airport.

**What happens to my seat if I forget to check in online?**
If you already had an assigned seat, you usually keep it and just check in at the airport. If you had no seat, one is assigned at check-in; on a full flight, late check-in raises the risk of being bumped.

**Do I go straight to security if I checked in online?**
Yes, if you have no bags to check and your boarding pass is on your phone or printed.

**How soon before a flight can I check in online?**
Most airlines open online check-in 24 hours before departure; some open it 48 hours or earlier.

**Do I need a printed boarding pass after online check-in?**
Usually not; a mobile boarding pass works on most airlines. Some low-cost carriers or airports still require a printout.
