Why You Need To Always Check-In Early?

In the past I usually check in for my flight about 6 or 7 hours before the departure.

While it might seem like a simple step, but when I started to check in early, I discover that checking in early has several advantages:

  • Better seat availability: The earlier you check in, the more seating options you’ll have.

  • Less stress at the airport: You can skip long lines and go straight to security especially when traveling carry-on only.
  • Smooth boarding process: Having your boarding pass ready makes everything smoother.

For most standard economy tickets, you will need to pay in order to choose a seat, especially a window seat, or a step with more legroom.

Once you’ve completed check-in, the next steps depend on your baggage situation.

If You Have Carry-On Only

You can:

  • Head directly to clear the security
  • And then proceed to your departure gate

You’ll need to:

  • Go to the bag drop counter
  • Attach your baggage tag (if printed at a kiosk)
