How Brexit Will Affect Traveling To Italy (for UK and US visitors)

The decision by the United Kingdom to leave the European Union will undoubtedly have uncertain implications for the British people. The only certainty guaranteed by this so called ‘Brexit’ vote is that things will likely never be the same again for Britain in its relations with EU countries such as Italy. As such British tourists are likely to be the first group of Brits who will experience first hand the uncertain and little known consequences that might materialize as the UK negotiates itself out of the EU. Listed below are examples of some of the uncertain repercussions of the Brexit vote to British tourists who wish to travel to Italy.

1. Costly Visas

Brexit has meant that, for the Brits at least, the days of the freedom of movement of people throughout Europe looks likely to be a thing of the past. Brits might now be treated as non-EU citizens, meaning that it is highly likely that they will be unable to cross a border-less EU without frequent passport checks. If any British national wishes to travel to Italy, it is probable that they will have to apply for and purchase a visa. This will mean that Brits will be subject to visa restrictions upon the amount of time they are permitted to stay within Italy before renewing their visa at an additional cost.

2. Poor Exchange Rate

As the full economic repercussions of the Brexit vote will not be known for many years to come, global markets have naturally reacted negatively at the level of uncertainty created by such a vote. This has resulted in a general weakening of pound sterling against all other major currencies such as the euro, meaning that British tourists traveling to a country like Italy could potentially have reduced spending power. The knock-on effect of this being that they might have less expendable money to spend over the course of their vacation on things like food and drink, excursions and souvenirs.

3. Expensive Air Travel

The Brexit vote has also created uncertainty about UK access to EU airspace, which could mean that the UK will have no other option than to renegotiate its air space treaties with all 27 EU member states. This could potentially mean that all UK-based air travel companies might have to pay increased fees in exchange for access to EU airspace, which perhaps will inevitably have to be passed onto the customer. This could spell the end of British access to cheap EU air travel, by forcing British tourists (and indeed non-EU tourists who fly from the UK specifically to access cheap EU flights) to pay more money for their flight to Italy from any UK airport.

Having said that we should also consider the possibility of less popular routes being abandoned by cheap no frills airlines due to higher costs, casting a shadow on smaller but crucial airports. Travelers from the U.S. too who often use Ryanair flights to Italy might have fewer choices in the future when it comes to air travel.

4. Increased Roaming Charges

The Brexit vote has also cast serious doubt over the UK’s continued access to cheap EU roaming charges, with many fearing that British telecom companies might have no other option than to charge British tourists higher roaming charges while they holiday in countries like Italy. Such a prospect could also negatively affect many non-EU tourists, such as those from the USA, who often purchase a UK sim card in order to take advantage of cheap EU call charges.

5. High-Cost Healthcare

Although not confirmed by either country, the UK’s decision to leave the EU has technically terminated the right of British citizens to be treated by the Italian Health Service while on holiday. This is still far from being a certainty, but if this is to be the case, then in future British tourists might have to procure and manage their own healthcare while on vacation in Italy. If both the UK and Italian governments are able to sort out a bilateral deal over the provision of healthcare to British tourists, it is likely that such an arrangement will charge British tourists for access to the Italian Health Service. However this is speculative and far from certain.
US travelers emergency treatment in Italy is still based upon US Healthcare coverage as well as International Travelers Insurance voluntarily acquired.
Overall the effects of Brexit on British tourists who wish to travel to Italy will in all likelihood be largely negative in nature. For a start Brits might find that the price of a holiday to Italy will be much higher than when the UK was a member of the EU, largely because of a poor sterling exchange rate with the euro and the fact that many benefits of being a member of the EU, such as visa free travel and access to healthcare, might now come with a costly price tag. In short, Brexit has potentially cost British tourists more money in order to travel to Italy and given them fresh uncertainty over simple things like roaming charges and more substantial issues such as access to the Italian Health Service when injured or ill.
