As the Biden administration nears the end of its term, it proposes significant new consumer protection regulations for airline passengers including cash compensation for cancelled flights and mandatory accommodations. The $200 starting compensation would escalate to up to $775 for delays, with public comment period for feedback. Airlines express concerns about increased costs. The proposal aims to bring U.S. regulations in line with European standards. Transportation Secretary Pete Buttigieg emphasizes bipartisan support for enhanced protections, urging the next administration to uphold these regulatory measures.
