Connecting flights: separate bookings

Question

I have booked the following flights:

1. Flight from London to Milan (MXP) with British Airways, arriving at Terminal 1.
2. Flight from Milan (MXP) to Dar es Salaam via Jeddah with Saudia, departing from the same Terminal (Terminal 1).

These flights have been booked separately - the onward flight departs three hours after I land at MXP on the same day.

NB:

• I am a Tanzanian citizen holding a British residence permit.
• I only have hand luggage
• I will check in online for my second flight (so the boarding pass will be available on my phone prior to my first first)

Can someone tell me whether or not I will have any issues transiting through MXP airside during the layover (can I just wait in the Transit area for flight 2)? The website of the Italian Foreign Ministry suggests that I will not require an Airport Transit Visa but I remember reading elsewhere that certain airlines can deny boarding under such circumstances.

Many thanks in advance for your help!

Answer 1

BA can, and is even likely to, deny you access to the first flight if you do not have the right to enter Italy, which means a full Schengen zone visa.

Airlines can allow you on a flight if you can convince them you will leave the country they fly you to but it is not a right, and even when you have their permission on paper the ground crew for the airline can stop you getting on.

I checked for you on a link from this question/answer:
Do I need a visa to transit (or layover) in the Schengen area?

You need to be allowed into Italy as if you have a layover or visit there and I see you not being allowed in without a visa.
