March web traffic growth shows demand could be declining
A look at web traffic for the month of March to the ten largest U.S. airlines shows that after the year got off to a strong start in January with 25% growth, year-over-year, and February saw 9% growth, March actually saw a decline dropping 3%. For the quarter, Q1 grew 10%, but those gains were front-end loading with most of the growth occurring in January. This could be the start of signs of slowing demand.
Five of ten peers saw year-over-year traffic declines in March, with the worst being Allegiant, which saw a 16% drop, followed by Southwest (-11%) and American (-9%). Among gainers, United and Frontier both saw a 10% rise in visits, followed by 9% growth at Spirit. Delta saw a 3% rise in visits. JetBlue was up 0.04%, which you can’t really pick out in the below chart.
