Yes, it is highly recommended and often necessary to have your boarding pass for your connecting flight before you even board your first plane. If your entire journey is booked under a single ticket (PNR), the airline will usually issue all boarding passes during your initial check-in. Having the second pass ready allows you to head straight to your next gate without standing in line at a transfer desk, which is crucial during tight connections. In 2026, most travelers use digital boarding passes saved in their mobile wallets, which update in real-time with gate changes. If you booked separate tickets (self-transfer), you will definitely need to check in again for the second leg, often requiring you to exit the secure area, collect bags, and go through security again. Even on a single ticket, international connections sometimes require a document check at the transit airport where a "gate-issued" pass might be required. Regardless of the scenario, having the second pass (or the digital confirmation) ensures you have proof of travel for security checkpoints and immigration officers during your transit.
