The long-standing debate over tipping in the United States has extended to the airport lounge, with United Airlines passengers sharply divided on the etiquette of tipping bartenders. The issue gained traction on social media platforms, particularly Reddit, where travelers are questioning whether gratuities are expected or appropriate in United Club lounges, especially when drinks and food are already included with lounge access.

Opinions vary widely among passengers. Some argue that tipping is a matter of good manners and customary practice, particularly for alcohol service. These travelers often suggest a guideline of $1 for a simple drink and $2 for a more complex cocktail, a practice sometimes described by travel experts as customary rather than mandatory.

Conversely, a significant number of passengers assert that they have never tipped in an airport lounge and have no intention of starting. They question the necessity of tipping when services and refreshments are part of the lounge access fee. For some, the tipping debate is symptomatic of a broader frustration with what they perceive as an ever-expanding tipping culture in the U.S.

"Tipping is out of control, no never in lounges," one passenger stated on Reddit. Others expressed a more nuanced view, suggesting that while tipping should be acceptable for those who wish to do it, the expectation of doing so should be eliminated. "Tipping can stay. The expectation of tipping is what needs to go away," another user commented.

United Airlines does not have a stated policy requiring passengers to tip lounge staff, and declining to leave a gratuity does not violate any airline rules. The nature of the service can also influence passenger perceptions. While self-service buffets might not prompt tipping, cocktail service from a bartender can feel more akin to a conventional bar setting. Some lounge workers may also be employed by third-party contractors rather than directly by United.

Airport lounges, with their origins tracing back to the 1930s with American Airlines' Admirals Club, have evolved from simple waiting areas into premium spaces offering extensive amenities. This transformation, including the provision of complimentary food and drinks, has further complicated the tipping question for many patrons. The debate reflects a cultural tension over when and where tipping is considered appropriate in the U.S., with airport lounges now a new focal point for this ongoing discussion.
