If all you have left in your passport was a half-page, then I can definitely understand the check-in agent's misgivings.
The number of remaining blank pages a passport should have is also an issue. Some travellers have reported arriving with one or less than one full page left and waiting for hours at immigration, until an official reluctantly grants them entry. The FCO lists no hard and fast rules because, in many cases, there aren't any.
A passport valid for a minimum of six months beyond the visa issuance and a valid visa are required for travel to Tanzania. Visitors who enter on visas must present a roundtrip ticket and demonstrate they have sufficient funds for their stay in Tanzania. Ensure you have at least one completely blank visa page prior to entering the country. U.S. citizens with valid passports may obtain a visa from the Embassy of Tanzania before arrival in Tanzania or at any port of entry staffed by immigration officials. The U.S. Embassy recommends that U.S. citizens obtain their visas before arriving in Tanzania to avoid potential delays at entry points. The current fee for a visa is US $100 for a 12-month multiple-entry tourist visa. Some border posts and embassies may make hand-written annotations on the computer printed visa due to technical difficulties. Be prepared to show your passport and explain your visa status when entering or departing Zanzibar or when traveling around the mainland.
