ETUSA Bus Line 100

20–45 DZD gets you from ALG to town on ETUSA 100

ETUSA Bus Line 100 runs from Houari Boumediene Airport’s International Terminal area toward Algiers for about 20–45 Algerian dinar, so it’s the rock-bottom option if you’re counting every centime. Buses usually show up roughly every 30 minutes and the ride into the city takes around 30–45 minutes in light traffic, longer in rush hour.

The stop for line 100 sits outside the main International Terminal (T1/T2 zone), in the same cluster as lines 39 and 178, which most guides list together as serving ALG. You pay the driver directly in cash, and locals recommend having small notes or coins ready in dinar because drivers are not set up to break big 1,000 DZD bills for airport riders.

Inside the bus, expect the same setup as line 39: basic city seating, almost no dedicated luggage space, and standing passengers once you leave the airport area. Crowding is common on daytime trips, and with fares around 20–45 DZD you’ll be shoulder‑to‑shoulder with commuters rather than other travelers with suitcases.

Routing is the tricky part. Line 100 appears in airport shuttle guides with lines 39 and 178, but there’s almost no English‑language detail about its exact stops, so many visitors cannot tell which line gets closest to their hotel in areas like Bab El Oued or Didouche Mourad. Several forum reports mention that bus 100 does not finish right in the historic center, which means adding a tram, metro, or short taxi ride at the end.

Regulars in Algiers treat 39 and 100 as interchangeable for the airport hop and just board whichever bus shows up first in that 30‑minute window, then transfer downtown to tram or metro at a known hub. That habit keeps total travel time closer to the 30–45 minute estimate instead of waiting longer at the terminal for a “better” route that may not exist.

Watch out for late‑day traffic between the airport road and central Algiers, which can stretch the ride on line 100 well past 45 minutes and wipe out the benefit of the 20–45 DZD fare if you’re trying to make an evening train or domestic flight from Terminal 4. If your schedule is tight, build an extra 30 minutes into your plan or skip the bus and pay for a taxi.

Practical tip: Before flying into ALG, screenshot a recent ETUSA 100 map and pin your hotel on an offline map, so you know in advance where to hop off and how you’ll connect by tram, metro, or taxi once the bus reaches the city.
