In an 8-K filed Tuesday morning, Delta said it was raising revenue guidance due to momentum in demand, citing strength across the main cabin, premium, loyalty and more. The airline also said its domestic and international unit revenues are growing in the mid-single digits year over year. Delta added that it has its strongest balance sheet in the company’s history.Bastian said most of Delta’s revenue comes from higher-spending customers who still want to travel, as well as from corporate customers.”We’ve seen eight of the top 10 sales days in our history this quarter, and five of those just within the last two weeks, within just the last week of March,” he said. “Even with the war going on, our revenues, our bookings are up 25% year over year.”Last quarter’s bookings are a softer comparison as the airline dealt with customers pulling back over tariff concerns.Choose CNBC as your preferred source on Google and never miss a moment from the most trusted name in business news. …
