3 hours clears the 90-minute international minimum connection time at George Bush Intcntl Houston, but you should still head directly to your gate. The Terminal Link automated train connects Terminals A, B, C and the D/E international complex airside, with rides typically taking 5-10 minutes between stops plus walking and waiting time. International arrivals must first pass through Customs and Border Protection in the D/E Federal Inspection Station before any connecting travel, and there is no sterile international-to-international transit corridor, so U.S.-bound international connections always require a full recheck.
