If you already have your digital or printed boarding pass and you are not checking any luggage, you generally do not need to check in at the gate; you can head straight through security to your departure gate. However, there are a few important exceptions to this rule. On international flights, some airlines require a "Document Check" to verify your visa or passport before boarding. In these cases, your digital boarding pass might say "See Agent" or "This is not a boarding pass." If this happens, you should visit the gate podium as soon as you arrive. Additionally, if you are flying on a "Basic Economy" ticket or with a low-cost carrier that has strict cabin bag size limits, agents may sometimes ask passengers to step forward for a quick bag check. Furthermore, if the flight is overbooked, agents may call your name to offer incentives for taking a later flight or to update your seat assignment. Unless you hear your name called or your pass indicates a document issue, you can simply wait for your boarding group to be announced.
