An appeal heard in June by the Upper Tribunal ruled in favor of British Airways on Monday, dismissing the claim by HM Revenue and Customs (HMRC). The tribunal found that the accommodation was a necessary expense related to travel for the airline's operations.

New aviation safety regulations introduced in 2016 mandated that cabin crew stay in hotels to rest between consecutive flights. The Tribunal concluded that this accommodation was a "necessarily incurred" cost to meet performance standards tied to their employment duties.

HMRC had contended that the accommodation costs should be classified as 'general earnings,' making them subject to income tax and national insurance contributions. However, the judges stated that the entire flight rotation, including stopovers, constitutes the job and the journey.

An HMRC spokesperson indicated that the department is carefully considering the tribunal's judgment. British Airways expressed satisfaction with the decision, noting that the Upper Tribunal found in their favor.
