In a repeat of late Aprilâs trend, an optimistic outlook from United Airlines Holdings (NASDAQ:UAL
+7.2%) is leading travel stocks higher on Tuesday. 
The air carrier provided an update in Tuesdayâs pre-market hours, stating that an already rebounding demand picture has continued to improve. The marked improvement motivated the company to raise revenue forecasts for the full year.
The commentary on stronger than expected demand is particularly notable given United Airlines (UAL) CEO Scott Kirby called the demand environment âthe strongest it's been in 30 yearsâ only about a month ago. Shares of United Airlines (UAL
+7.2%) gained over 7% in afternoon trading, building back from some turbulence felt in mid-may.
The optimistic outlook for summer travel spread beyond simply United's stock however. Indeed, the update encouraged much of not only the US airline sector, but travel services and hospitality to tick higher on Tuesday.
