If a no-deal Brexit does occur, these are some of things the general public can come to expect while travelling to the EU:
1 – Longer Wait Times at the Airport

Starting things off with one of the more minor inconveniences: wait times to both enter and exit the country will be increased considerabley if a no-deal Brexit occurs. Whilst this may seem trivial in comparison to many other issues, this is something that will affect almost everyone. This will be due to British travellers being classified as third country nationals under the Schengan Border Code.
2 – New Passport Validity Rules

The UK will be getting a passport redesign regardless of what Brexit deal is agreed upon! Other than that though, its bad news for travellers if no deal is made. The Schengan Border Code means that third country nationals must have a passport issued within the last 10 years and at least 6 months remaining before expiry. Additionally, we will only be allowed to spend a maximum of 90 days within the EU Schengan Area.
3 – Flight Permission Issues

As it stands today, airlines currently have automatic permission to operate flights between the UK and the EU without having to seek individual permissions from respective states. In the event of a no-deal Brexit, airlines will have to be granted individual permissions when operating UK-EU flights and vice versa. This could mean that countries deny their borders to UK airlines, and could lead to several cancellations and delays, especially surrounding March 29th.
4 – Pet Passports

Without a Brexit deal, the UK could become an unlisted third country under the EU Pet Travel Scheme. This would mean that pet owners would have to take their pets to the vets 4 months before going to the EU. They would also have to ensure that their pet had a blood titre test at least three months prior to flying, and enough rabies antibodies were present.
5 – No Visas!

Thankfully, The European Commission have ruled that British citizens will have to pay 7€ every three years in order to be able to travel to the EU. This is favourable compared to the potential costs of visas, which could range up to hundreds of pounds.
