Yes, you can absolutely travel with a briefcase in 2026, and it is a premier choice for professionals looking to maintain a high-quality "business-ready" appearance. Most airlines categorize a standard briefcase as a "personal item" rather than a carry-on, provided its dimensions are roughly 18 x 14 x 8 inches or smaller. This high-value distinction allows you to bring a briefcase in addition to a rolling suitcase, keeping your laptop, documents, and chargers tucked safely under the seat in front of you for easy access. If your briefcase is exceptionally large or a hard-sided "attaché" style, it may be treated as a carry-on and stored in the overhead bin. For 2026 travelers, choosing a briefcase with a "trolley sleeve" is a "pro-move," allowing it to slide securely onto your suitcase handle for a frictionless transit through the terminal.
