Airline ticket prices are starting to climb as carriers respond to rising jet fuel costs tied to the war in Iran. Cathay Pacific, Air France-KLM and a handful of other carriers already have raised their fares or added fuel surcharges. United Airlines CEO Scott Kirby has warned that higher ticket prices will “probably start quickly.” Experts say it’s not a question of if airfares rise, but when and by how much — especially on long-haul international routes. The security director of a global risk management company advises travelers to book early, set fare alerts and use frequent flyer miles or credit card points instead of holding out for a perfect deal.

The National Museum of African American History and Culture is removing a rare slave ship timber from its “Slavery and Freedom” exhibit and sending it back to South Africa. On March 22, visitors will have their last chance to see the piece on display in Washington. The museum says the change follows a loan agreement that ends July 1. Staff members also cite conservation needs because the wood is fragile. The timber comes from the São José, a Portuguese ship that sank off the coast of South Africa in 1794. Researchers recovered the wreck in 2015. The museum plans to replace the timber with a cargo manifesto.
