In 2026, the ability to sit together on a Basic Economy ticket is highly restricted and not guaranteed. Most major airlines, such as United, Delta, and American, utilize automated seat assignments that are finalized just before boarding, often placing travel companions in middle seats or separate rows. However, there are 2026 "workarounds": many airlines now allow Basic Economy passengers to purchase a seat assignment for a fee (typically $15–$45) during the check-in window. Additionally, US Department of Transportation regulations in 2026 have strengthened "family seating" rules, requiring airlines to seat children under 12 with at least one adult at no extra cost, provided there is availability at the time of booking. If you are a group of adults on a 2026 Basic Economy fare, your best bet is to arrive at the gate early and politely ask the agent if any adjacent seats are open, though you should prepare for the high probability of being separated.
