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 4Y 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 4Y brand counts as 4Y metal; flights 4Y markets but another airline operates don't. ### Airbus A320 Narrowbody · Filed as 32A **Nonstop routes**\ 182 **Airports served**\ 58 **Typical route**\ 1,080 mi Longest route: [Munich (MUC) to Sta Cruz de la Palma, La Palma Island (SPC)](https://2lnr.com/routes/muc-spc.md), about 2,080 miles. #### Routes it flies most - [Frankfurt (FRA) to Pusignan (LYS)](https://2lnr.com/routes/fra-lys.md) - [Pusignan (LYS) to Frankfurt (FRA)](https://2lnr.com/routes/lys-fra.md) - [Frankfurt (FRA) to Palma de Mallorca (PMI)](https://2lnr.com/routes/fra-pmi.md) - [Munich (MUC) to Pusignan (LYS)](https://2lnr.com/routes/muc-lys.md) - [Larnaca (LCA) to Munich (MUC)](https://2lnr.com/routes/lca-muc.md) - [Palma de Mallorca (PMI) to Frankfurt (FRA)](https://2lnr.com/routes/pmi-fra.md) [The other 176 routes on the 4Y route map](https://2lnr.com/routes/airlines/4y.md) ### Airbus A330-300 Widebody · Filed as 333 **Nonstop routes**\ 41 **Airports served**\ 19 **Typical route**\ 4,810 mi Longest route: [Port Louis (MRU) to Frankfurt (FRA)](https://2lnr.com/routes/mru-fra.md), about 5,720 miles. #### Routes it flies most - [Calgary (YYC) to Frankfurt (FRA)](https://2lnr.com/routes/yyc-fra.md) - [Windhoek (WDH) to Frankfurt (FRA)](https://2lnr.com/routes/wdh-fra.md) - [Frankfurt (FRA) to Tampa (TPA)](https://2lnr.com/routes/fra-tpa.md) - [Frankfurt (FRA) to Calgary (YYC)](https://2lnr.com/routes/fra-yyc.md) - [Orlando (MCO) to Frankfurt (FRA)](https://2lnr.com/routes/mco-fra.md) - [Frankfurt (FRA) to Orlando (MCO)](https://2lnr.com/routes/fra-mco.md) [The other 35 routes on the 4Y route map](https://2lnr.com/routes/airlines/4y.md) ### Airbus A330-200 Widebody · Filed as 332 **Nonstop routes**\ 14 **Airports served**\ 10 **Typical route**\ 4,700 mi Longest route: [Frankfurt (FRA) to Cancun (CUN)](https://2lnr.com/routes/fra-cun.md), about 5,350 miles. #### Routes it flies most - [Orlando (MCO) to Frankfurt (FRA)](https://2lnr.com/routes/mco-fra.md) - [Philadelphia (PHL) to Frankfurt (FRA)](https://2lnr.com/routes/phl-fra.md) - [Frankfurt (FRA) to Orlando (MCO)](https://2lnr.com/routes/fra-mco.md) - [Tampa (TPA) to Frankfurt (FRA)](https://2lnr.com/routes/tpa-fra.md) - [Frankfurt (FRA) to Philadelphia (PHL)](https://2lnr.com/routes/fra-phl.md) - [Frankfurt (FRA) to Tampa (TPA)](https://2lnr.com/routes/fra-tpa.md) [The other 8 routes on the 4Y route map](https://2lnr.com/routes/airlines/4y.md) ### Airbus A321 Narrowbody · Filed as 321 **Nonstop routes**\ 3 **Airports served**\ 3 **Typical route**\ 1,310 mi Longest route: [Frankfurt (FRA) to Las Palmas (LPA)](https://2lnr.com/routes/fra-lpa.md), about 1,980 miles. #### Routes it flies most - [Frankfurt (FRA) to Heraklion (HER)](https://2lnr.com/routes/fra-her.md) - [Frankfurt (FRA) to Las Palmas (LPA)](https://2lnr.com/routes/fra-lpa.md) - [Heraklion (HER) to Frankfurt (FRA)](https://2lnr.com/routes/her-fra.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 4Y 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 4Y 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 4Y 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 Discover Airlines - [Where 4Y flies: the Discover Airlines route map](https://2lnr.com/routes/airlines/4y.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 Discover Airlines (4Y) aircraft **What aircraft does Discover Airlines fly?** Four aircraft types appear on Discover Airlines' own metal in 2LNR's schedule data, reaching 75 airports, including Airbus A320, Airbus A330-300, and Airbus A330-200. 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 4Y brand is counted as 4Y metal; flights 4Y markets but another airline operates are not. **Does 2LNR publish 4Y seat maps by aircraft type?** Not as static diagrams. 2LNR reads the LIVE seat map for a specific 4Y 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 4Y 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 4Y cabin diagram was never able to do. **Where does this 4Y fleet information come from?** From the schedules 2LNR collects continuously and uses to build its own route map: every aircraft listed here is one 4Y 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 4Y 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 Discover Airlines flies?** Of the routes in 2LNR's schedule data, the longest 4Y operates on its own metal is Port Louis (MRU) to Frankfurt (FRA), about 5,720 miles great-circle, flown on the Airbus A330-300. 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: 4Y schedules more than one type on many of its routes. ## See the seats on your 4Y flight Free to start.
