Lufthansa chief executive Carsten Spohr has said that flight prices will never return to where they were before the pandemic, forecasting stable or increasing prices in future.
Tickets selling for under €20 was irresponsible and too low, Spohr said at an event in Berlin.
The industry needed rising prices to finance greater investment and be more resilient to shocks like the Covid-19 pandemic, he added.
Still, a recession was to be expected at this stage in Germany, the chief executive warned, which would dampen consumer demand.
Last month Ryanair's group chief executive also said the airline's trademark €1 and €10 fares will not be seen for a "number of years" due to soaring fuel prices.
Michael O'Leary said he expected Ryanair's average fare to rise by about €10 over the next five years, from around €40 last year to roughly €50 by 2027.
"There's no doubt that at the lower end of the marketplace, our really cheap promotional fares - the €1 fares, the 99 cent fares, even the €9.99 fares - I think you will not see those fares for the next number of years," he stated.
