United Airlines Holdings Inc. will begin charging customers more to access its airport lounges to help combat a rise in overcrowding since the pandemic. Individual United Club memberships will now cost $750 or 94,000 reward miles a year for MileagePlus loyalty program members, the company said in a message to customers on Monday. The company is also adding a new “All Access” membership tier priced at $1,400 or 175,000 miles that extends lounge access to certain guests traveling with a member.  Previously, United Club annual fees peaked at $650 or 85,000 miles.  Since the pandemic subsided, travelers rushed to access the amenity-rich spaces by enrolling in airline loyalty programs and acquiring carrier-branded credit cards, part of a growing demand for premium experiences. The clubs provide free food, drinks and comfortable seating. They’re a key perk of frequent-flyer programs and co-branded credit cards — a major revenue stream for airlines. Major U.S. carriers are now trying to tame the crowds inside their plush lounges that have become more of a nuisance in recent years, with long lines sometimes spilling into airports. Airlines have opened more locations and added larger and more premium facilities with limited access to help address the issue.  United’s latest changes take effect Monday, but current benefits will remain in place until existing memberships expire, the company said.
