Knowing which one operates your departure is the first thing to settle before you pick a seat, because cabins differ far more between airframes than between rows. Each aircraft below opens the nonstop routes S4 flies it on, with the longest of them and the configuration on file where there is one. Updated October 23, 2026.

Regional flying under the S4 brand counts as S4 metal; flights S4 markets but another airline operates don't. ### Airbus A321neo family Narrowbody · Filed as 32Q **Nonstop routes**\ 30 **Airports served**\ 13 **Typical route**\ 1,590 mi Longest route: [Boston (BOS) to Praia (RAI)](https://2lnr.com/routes/bos-rai.md), about 3,390 miles. #### Routes it flies most - [Lisbon (LIS) to Ponta Delgada (PDL)](https://2lnr.com/routes/lis-pdl.md) - [Ponta Delgada (PDL) to Lisbon (LIS)](https://2lnr.com/routes/pdl-lis.md) - [Porto (OPO) to Ponta Delgada (PDL)](https://2lnr.com/routes/opo-pdl.md) - [Ponta Delgada (PDL) to Boston (BOS)](https://2lnr.com/routes/pdl-bos.md) - [Boston (BOS) to Ponta Delgada (PDL)](https://2lnr.com/routes/bos-pdl.md) - [Toronto (YYZ) to Ponta Delgada (PDL)](https://2lnr.com/routes/yyz-pdl.md) [The other 24 routes on the S4 route map](https://2lnr.com/routes/airlines/s4.md) ### Airbus A320 Narrowbody · Filed as 320 **Nonstop routes**\ 18 **Airports served**\ 9 **Typical route**\ 970 mi Longest route: [Ponta Delgada (PDL) to Frankfurt (FRA)](https://2lnr.com/routes/pdl-fra.md), about 1,880 miles. #### Routes it flies most - [Lisbon (LIS) to Ponta Delgada (PDL)](https://2lnr.com/routes/lis-pdl.md) - [Ponta Delgada (PDL) to Porto (OPO)](https://2lnr.com/routes/pdl-opo.md) - [Ponta Delgada (PDL) to Lisbon (LIS)](https://2lnr.com/routes/pdl-lis.md) - [Praia da Vitoria (TER) to Lisbon (LIS)](https://2lnr.com/routes/ter-lis.md) - [Lisbon (LIS) to Praia da Vitoria (TER)](https://2lnr.com/routes/lis-ter.md) - [Horta (HOR) to Lisbon (LIS)](https://2lnr.com/routes/hor-lis.md) [The other 12 routes on the S4 route map](https://2lnr.com/routes/airlines/s4.md) ### Airbus A320neo Narrowbody · Filed as 32N **Nonstop routes**\ 5 **Airports served**\ 4 **Typical route**\ 970 mi Longest route: [Barcelona (BCN) to Ponta Delgada (PDL)](https://2lnr.com/routes/bcn-pdl.md), about 1,490 miles. #### Routes it flies most - [Lisbon (LIS) to Praia da Vitoria (TER)](https://2lnr.com/routes/lis-ter.md) - [Ponta Delgada (PDL) to Lisbon (LIS)](https://2lnr.com/routes/pdl-lis.md) - [Lisbon (LIS) to Ponta Delgada (PDL)](https://2lnr.com/routes/lis-pdl.md) - [Barcelona (BCN) to Ponta Delgada (PDL)](https://2lnr.com/routes/bcn-pdl.md) - [Ponta Delgada (PDL) to Barcelona (BCN)](https://2lnr.com/routes/pdl-bcn.md) ### De Havilland Canada Dash 8-400 Turboprop · Filed as DH4 **Nonstop routes**\ 4 **Airports served**\ 3 **Typical route**\ 660 mi Longest route: [Funchal (FNC) to Praia da Vitoria (TER)](https://2lnr.com/routes/fnc-ter.md), about 710 miles. #### Routes it flies most - [Funchal (FNC) to Ponta Delgada (PDL)](https://2lnr.com/routes/fnc-pdl.md) - [Ponta Delgada (PDL) to Funchal (FNC)](https://2lnr.com/routes/pdl-fnc.md) - [Funchal (FNC) to Praia da Vitoria (TER)](https://2lnr.com/routes/fnc-ter.md) - [Praia da Vitoria (TER) to Funchal (FNC)](https://2lnr.com/routes/ter-fnc.md) Route counts are distinct directional nonstop city pairs in 2LNR's schedule data. Where an airline files a family code without naming a variant, the card reads as the family: that's what was filed, and guessing the airframe would be worse than saying so. Distances are great-circle miles between the two airports, rounded to the nearest ten, not the track a flight actually files. A longest route is shown only where every one of that aircraft's routes could be measured, and a typical route only where most of them could; where the measurement was too thin, the figure is left out rather than estimated. ## How to see the seat map for your S4 flight The useful version of this question is per flight, not per aircraft type. ### Add the flight, then open its live map On Pro, 2LNR reads the seat map for the specific S4 flight and date you're looking at, scores the open seats inside your own cabin and marks paid seats as paid. It's read at the moment you ask rather than stored, so an aircraft swap shows up as a different map instead of a wrong one. ### Then let it watch Cabins churn in the last days before departure as blocked rows release and upgrades clear. Seat monitoring re-reads the map on a cadence that tightens as departure approaches and tells you when a better seat opens, or when the seat you hold changes underneath you. More on that in [seat monitoring](https://2lnr.com/lp/seat-monitoring.md). ### If you want a cabin diagram instead 2LNR doesn't publish stored cabin drawings or per-seat comfort ratings for S4 aircraft, and this page won't pretend otherwise. For browsing a layout on an aircraft you haven't booked, a maintained diagram library such as [AeroLOPA](https://www.aerolopa.com/) is the right tool. ## More on Azores Airlines - [Where S4 flies: the Azores Airlines route map](https://2lnr.com/routes/airlines/s4.md) - [Seat maps by airline and aircraft](https://2lnr.com/seatmaps.md) - [How to read an airline seat map](https://2lnr.com/guides/airline-seat-maps.md) - [What replaced SeatGuru](https://2lnr.com/compare/seatguru.md) ## Frequently asked questions about Azores Airlines (S4) aircraft **What aircraft does Azores Airlines fly?** Four aircraft types appear on Azores Airlines' own metal in 2LNR's schedule data, reaching 16 airports, including Airbus A321neo family, Airbus A320, and Airbus A320neo. The full list is on this page, with the nonstop routes each one operates and the recorded cabin configuration where there is one. Regional flying under the S4 brand is counted as S4 metal; flights S4 markets but another airline operates are not. **Does 2LNR publish S4 seat maps by aircraft type?** Not as static diagrams. 2LNR reads the LIVE seat map for a specific S4 flight and date, which is a different thing from a stored cabin drawing: an aircraft swap shows up as a different map rather than a wrong one. If you want to browse a cabin layout for an aircraft you have not booked, a maintained seat-map library such as AeroLOPA is the right tool, and this page says so rather than pretending otherwise. **How do I see the seat map for my S4 flight?** Add the flight to 2LNR and open it. Pro plans pull that departure's live seat map, score the open seats inside your own cabin, and mark paid seats as paid. 2LNR can then keep watching the map for a better seat, which is the part a static S4 cabin diagram was never able to do. **Where does this S4 fleet information come from?** From the schedules 2LNR collects continuously and uses to build its own route map: every aircraft listed here is one S4 has filed against a nonstop route it operates, and the counts are the routes in that data. It is a picture of what is scheduled, not an aircraft register, so a type S4 owns but is not currently scheduling will not appear. Route lengths are great-circle distances between the two airports rather than flown track miles. **What is the longest route Azores Airlines flies?** Of the routes in 2LNR's schedule data, the longest S4 operates on its own metal is Boston (BOS) to Praia (RAI), about 3,390 miles great-circle, flown on the Airbus A321neo family. That is the distance between the two airports rather than the track the flight actually takes, and it is the routing rather than the aircraft that decides it: S4 schedules more than one type on many of its routes. ## See the seats on your S4 flight Free to start.
