Airlines are offering 'basic premium' fares. Beware the potential catch.

JetBlue is introducing discounted 'Base' fares for its upcoming BlueFirst first-class cabin, which exclude seat selection and limited cancellation options. The airline joins Delta and United in adopting a 'basic premium' pricing model, offering lower fares but requiring passengers to pay extra for previously standard amenities. Critics warn this trend could lead to hidden costs, as airlines historically add fees for services once included in ticket prices.
