Delta Air Lines Inc. on Wednesday said it sees an opportunity to tap into affluent travelers as it laid out its long-term goals the next three-to-five years.

Refundable tickets, extra leg space, and free boozy beverages have featured prominently in airlines' multiyear strategies as executives announce new premium passenger investments to woo travelers and investors.

Delta Air Lines said on Wednesday it expects 2025 revenue to grow by a mid single-digit percentage as it strengthens its bet on premium travel, a major revenue driver for the carrier.

Delta Air Lines said it sees significant room for its premium offerings to continue growing over the next several years, as it notes a "thriving" premium consumer.
