Most terminal mistakes happen on departure day, not arrival day.

The core distinction

A1 serves Terminal 1
A2 serves Terminal 2

That sounds obvious—until your airline changes gate plans or you assume “airport is airport.”

What changes for travelers

Topic	T1	T2
Typical feel	Newer, larger flow	More segmented areas
Aerobus line	A1	A2
Common risk	Extra walking time	Wrong sub-terminal assumptions

Field notes

Verify terminal in your airline app 24h before flight.
Recheck again on departure morning.
Match Aerobus line accordingly.

Bottom line

In Barcelona, terminal precision is everything. One letter—A1 vs A2—can save or sink your timing.
