A surge in travel insurance policies being taken out is likely during summer, as air-control authorities and geologists warn of further flight disruptions due to volcanic ash.
The experts say that the volcanic ash from Iceland could lead to more cancellation of flights across Europe throughout the busy holiday period.
The warning came after computerised projections attempt to show where the ash clouds will float next, despit being at the whims of shifting winds.
Einar Kjartansson, a geophysicist at the Icelandic Meteorological Office, said: "We do not pretend to be psychics." Since the volcanic eruptions started the expert has often been asked to predict the volcano's next move.
During April 15-20, flights across much of Europe were severely disrupted due to huge volumes of ash, forcing around 10 million passengers to remain stranded.
Since then the ash plume has thinned and spread out, shifting shape by the hour, rising into North Atlantic air routes and imposing awkward detours on hundreds of trans-Atlantic flights daily.
