SEATTLE-<\/strong> United Airlines (UA)<\/a> introduced the Boeing 777 in 1995 from Chicago O\u2019Hare International Airport (ORD). Since then, airlines such as British Airways (BA)<\/a> from London Heathrow (LHR) and Cathay Pacific (CX) from Hong Kong International Airport (HKG) have relied heavily on the aircraft for long-haul travel.<\/p>\n\n\n\n

Passengers often report feeling unwell after flights on the Boeing 777. Unlike newer jets such as the Boeing 787 Dreamliner (introduced by ANA at Tokyo Narita) or Airbus A350 (launched by Qatar Airways from Doha), the 777 frequently leaves travelers with flu-like symptoms, fatigue, and sinus discomfort.<\/p>\n\n\n\n

Boeing 777 Flights Cause More Fatigue<\/h2>\n\n\n\n

Not all planes are equal when it comes to comfort. While First Class on a Boeing 777<\/a> is marketed as luxurious, many passengers describe the same post-flight discomfort as those seated in Economy. As one flyer wrote on Reddit:<\/p>\n\n\n\n

\n

\u201cMan, my second long haul on a 777 this year and I always feel like absolute CRAP after those flights.\u201d<\/p>\n<\/blockquote>\n\n\n\n

Another traveler added:<\/p>\n\n\n\n

\n

\u201cTotally agree, flew the 777 to Dallas and back last November and wasn\u2019t right for a few days after arriving in the US.\u201d<\/p>\n<\/blockquote>\n\n\n\n

These comments highlight a broader sentiment that the 777 leaves passengers feeling worse than comparable aircraft. According to PYOK<\/a>, cabin pressurization and humidity levels are primary factors behind this fatigue.<\/p>\n\n\n\n

Cabin Pressurization and Design<\/h2>\n\n\n\n

The Boeing 777 cabin is pressurized to between 6,000 and 8,000 feet, compared to about 6,000 feet on the 787 and A350<\/a>. While a difference of 2,000 feet might sound minor, over 10 to 15 hours, it has a substantial effect on oxygen levels, circulation, and energy.<\/p>\n\n\n\n
