The US-Europe transatlantic market is one of the most lucrative markets in the world. Airlines typically see excellent performance on routes in this market during the northern summer months. Capacity is also typically higher in this market, with the addition of seasonal leisure flights. Now, as Italy is welcoming Americans, airlines could be in for a better-than-expected summer for transatlantic travel.

Italy joins the list of reopenings

For Americans looking to go to Europe, four countries are now welcoming Americans. This includes Iceland, Greece, Croatia, and Italy. For travel to Italy, passengers have to be flying on one of the COVID-tested designated flights. The two US carriers currently running such flights are American and Delta.

Meanwhile, Iceland, Greece, and Croatia are relying on vaccinated passengers or, in the case of the latter two countries, those with negative test results to take a vacation. In all four of these countries, tourism is important to the local economy, and Americans have shown a willingness to travel to these destinations.

For airlines transporting passengers between these countries, the reopening presents an opportunity to reclaim a European summer. Between family, leisure, and business links between the US and Europe, the reopenings can be a big boon for airlines while reuniting passengers with family, culture, or business deals.

The EU is expected to open

Just a few weeks ago, the head of the European Union stated that she would like to see uniform guidelines to welcome Americans for tourism to Europe. June has been floated as the likely month for when much of Europe opens up for Americans.

However, these four countries are coming out ahead of the game and welcoming Americans. This could lead to some big rewards for those destinations. With June just around the corner, and Americans seeking to book getaways that are more certain to happen than others, countries that announce reopenings sooner rather than later are set to benefit.

Take, for example, Croatia, Iceland, and Greece. Shortly after it was clear all three countries were opened up for Americans, United Airlines announced new and resuming routes covering those destinations. The carrier, on the first day of announcing those routes, saw over 3,000 bookings. Passengers, showing a strong willingness to fly to Europe for a vacation, appear to reward destinations that have come to the front of the pack in reopening.

The longer other countries wait, the greater the possibility that Americans will vote with their wallets and secure travel to already open destinations. This could have ramifications in other countries that also rely heavily on tourism to power the local economy.

If more countries open up, then US and European airlines have a strong chance of reclaiming the summer transatlantic market. This could lead to a huge financial boon for airlines. With a chance to actually earn some revenue, this could also help save airline jobs and stimulate other sectors of the economy. Seeing other countries open up could be the incentive other European countries need to open their borders.

The holdouts: US and UK

There are two holdouts, however. The United States and the United Kingdom were expected to provide some good news for international travel this month, though neither has largely materialized. Airlines have pushedand will continue to push – for a broader reopening.

The US was expected to relax some travel restrictions from mid-May. This currently has not happened. However, given the abrupt public health guidance shift last week on face masks for vaccinated people, it is still possible that the US starts to relax its European travel bans.

The virus situation in Europe has been improving in the last few weeks. Coupled with increasing vaccinations, Europe does not show the same risks or signs as India, for example, and is far from the overwhelming surge in cases the continent saw a year ago. The US also has a policy mandating a negative test result for entry, even if passengers are fully vaccinated.

The UK also was expected to put the US on its Green List, enabling travel between the two countries without quarantine restrictions. That also did not materialize, and the UK chose to go with a more limited list of destinations.

The longer the UK and US hold out, the more likely it is that both countries will see more muted summers for air travel. This would be a huge disappointment for airlines looking to come back after over a year of near devastation.
