Dec 3 (Reuters) - U.S. budget carrier Frontier Airlines

said Tuesday it will offer first-class style seating to

woo passengers willing to spend more.

Frontier previously added more seats with extra leg room and

business fares targeted at small companies. In August, Spirit

Airlines ( SAVEQ ) began offering intra-Europe style business

class seats with a guaranteed blocked middle seat, while

Southwest Airlines ( LUV ) said in July it plans to offer

premium seats with extra leg room and end its open seating

practice.

Frontier CEO Barry Biffle said the airline hopes to begin

offering first-class seating on all flights in late 2025, which

will require approval from regulators. "There's a percentage of

our customers willing to pay more for comfort," Biffle told

Reuters. "These are affluent leisure customers who want a

first-class seat."
