The outlook looks a little bumpier for listed European airlines.
Why? Well, some clever research from a leading investment bank using the online equivalent of a weather radar has picked up some potential turbulence.
According to UBS, search interest in European airlines has declined year-on-year.
The Swiss bank runs what it calls an Evidence Lab Global Airline to monitor what's happening on the ground (and in the air).
The report, which analyses Google search data to gauge consumer interest, indicates a general weakening across major European travel markets.
Among the airlines surveyed, Ryanair Holdings PLC (LSE:RYA) maintained a strong presence, ranking in the top three across the five largest European travel geographies.
However, like many of its peers, Ryanair experienced a decrease in search interest compared to the previous year.
British Airways (owned by International Consolidated Airlines Group SA (LSE:IAG)) was the exception in the UK market, where it saw an increase in search activity.
UBS suggests that factors such as a shift in the Easter holiday calendar, a trend towards direct bookings, or a general softening in demand could be contributing to the overall decline in search interest.
So, don't panic yet.
That said, the prevailing investment thesis for the sector; that Trump tariffs, an impending trade war and a global economic slowdown will have a negative impact on fliers.
The UBS Evidence Lab utilises a proprietary method to normalise Google search data across various terms and regions, offering insights into consumer behaviour and potential market trends.
While search interest is just one indicator of consumer engagement, the downward trend highlighted in the report may signal challenges ahead for European airlines as they navigate a competitive and evolving market landscape.
