LONDON, June 21 (Xinhua) -- National holidays and a season of post-pandemic "revenge travel" have heaped pressure on already-strained U.S. airlines, the Guardian newspaper has reported.
According to an article published on Monday, 4,200 U.S. flights were delayed and 900 canceled on Father's Day (Sunday), bringing the total number of flights interrupted since Thursday to 19,000. Juneteenth, a federal holiday in the United States commemorating the emancipation of enslaved African Americans, and the holiday weekend also contributed to the disruptions.
