Almost half of travellers believe the global Covid-19 situation is improving.
Skyscanner research carried out in recent weeks shows 49% of consumers have a positive outlook, compared with 20% who believe it is “getting worse”.
In the week commencing 29 March, the most searched-for countries were the US, Spain, Russia, Turkey and the UK.
Skyscanner also reports reduced quarantine times are leading to surges in searches to popular destinations.
Thailand announced its quarantine time would be reduced to 10 days for vaccinated tourists and worldwide searches in March increased by 40.8% compared with February.
Domestic travel continues to drive recovery in some countries. There was a week-on-week increase in searches, of +316% for Atlanta and Fort Lauderdale, +170% for Boston and San Diego and +117% for Los Angeles and Maui Kahulu.
Skyscanner also noted uptick in bookings between London and Tel Aviv following reporting that Israel could be one of the first green list countries.
Hugh Aitken, vice-president flights at Skyscanner said: “With many travellers awaiting the green light for international travel to resume from their respective governments, Skyscanner data shows that there is a growing sense of optimism around the world.
“Where measures have been announced providing clarity on dates and restrictions, we see direct correlations with surges in demand. Domestic travel and international travel corridors are showing early signs of promise.
“While there is still some way to go, it’s clear that testing and vaccines are key enablers in unlocking travel. However, the industry’s recovery is dependent on how straightforward and standardised the processes on both ends of the journey are for travellers, in addition to clear and timely guidance on reopening.”
