Water & Hydration

Hydration notes pulled from the editorial guide.

From Water & Hydration

No drinking-fountain map and no bottled-water price were on the GIAA pages checked for this guide. TSA screens departures. A bottle bought before security is not a plan for the concourse unless it passes the checkpoint.

Lounges, Food & Amenities

Hydration notes pulled from the editorial guide.

From Lounges, Food & Amenities

Showers are unresolved. The 2010 opening release said the lounge would have showers, and a Mastercard lounge finder still lists one. The current airport lounge page and the English Priority Pass conditions do not. Do not count on a shower. The airport site also did not publish a restaurant directory, a bottle price, or an airport-wide Wi-Fi name on 24 September 2026. Free Wi-Fi is confirmed only inside Sagan Bisita.
