The best time is about 5-10 minutes from the time the airline opens the online check-in gate.

According to Scott Keyes, an expert on a website specializing in low-cost flight advice, usually, airlines will allow guests to check-in online 24 hours before the flight, so customers register for check-in as quickly as possible, the sooner the better.

"If you register for about 5-10 minutes right after the airline opens the online check-in service, you have more options. You will be able to choose a seat next to each other if you are in a group, or sit by the window or the aisle, the area above the cabin. This makes a lot of sense, especially if it's a full flight," Scott said. This expert thinks that you should precisely time the procedure.

However, choosing a seat in advance by online form also has disadvantages. That is, you will hardly be able to upgrade your seat compared to choosing a seat at the check-in counter. According to information from a British Airways flight attendant, passengers who choose their seats in advance will lose the opportunity to upgrade their seats for free on the flight. "Many guests asked to upgrade their seats when they greeted us at the door. Some even brought us, sweets, because they learned the tips online and thought they were helpful. In fact, we couldn't. Instead, you should ask for a free upgrade when you check-in at the airport check-in counter," she said.

You should check in early but leave your luggage at the airport late, close to the boarding time. Because when you check in early your luggage will go on the plane first and your suitcase will leave the plane last, this means your luggage will show up late at the carousel and the waiting time at our airport will be longer.
