Allegiant Air flies a single-class cabin across its entire fleet — no first class, no premium cabin in the traditional sense. What varies is the aircraft type, the configuration, and whether your specific plane has Allegiant Extra (Legroom+) rows available. Here’s exactly what the seat maps look like, what the numbers mean for comfort, and which seats are worth paying extra for.
Allegiant’s Fleet: Which Aircraft Will You Be On?
As of 2026, Allegiant operates three aircraft types, each with different seat configurations:
| Aircraft | Configurations | Total Seats | Standard Pitch | Allegiant Extra? |
| Airbus A319 | 1 config (156M) | 156 | 30″ (76cm) | No |
| Airbus A320 | 186M (older) | 186 | 28–30″ | No |
| Airbus A320 | 180M (newer) | 180 | 28–30″ standard | Yes — rows 1–5 at ~34″ |
| Boeing 737 MAX 8 | 190M | 190 | varies | No (USB ports at every seat) |
The aircraft type isn’t always displayed prominently at booking — checking the seat map during selection is the reliable way to know which configuration you’ll be on. Aircraft swaps before departure are common at Allegiant, so the configuration you see at booking isn’t guaranteed on the day of travel.
Allegiant Air A320 Seat Map: The Two Configurations
186-Seat A320 (Older Configuration)
The 186-seat A320 is Allegiant’s older layout — all standard seats, 3-3 configuration across 31 rows, with no premium or extra-legroom option. Seat pitch runs approximately 28 to 30 inches throughout. This configuration is being gradually phased out as Allegiant retrofits its A320 fleet to the 180-seat layout with Allegiant Extra rows. As of late 2025, roughly 70% of the A320 fleet had been retrofitted.
On the 186-seat layout, the best available seats for legroom are the exit rows. Avoid the last row (Row 31 area) — passenger reviews note an intermittent lavatory smell and limited recline clearance is irrelevant since seats don’t recline anyway, but the location next to the lavatories is a genuine comfort issue.
180-Seat A320 (Allegiant Extra Configuration)
The 180-seat A320 is the newer standard, identifiable by Rows 1–5 marked as Allegiant Extra or Legroom+ in the seat map. These rows offer approximately 34 inches of pitch — about 6 extra inches over the standard rows — along with upgraded seat padding, larger tray tables, and dark-blue-and-orange upholstery. Allegiant Extra is available as part of a bundle that includes priority boarding and a reserved overhead bin space, priced at $20–$51 depending on route.
If the seat map during booking shows rows 1–5 labeled differently from the rest of the cabin, you’re on the 180-seat configuration. If all rows appear identical, it’s the 186-seat layout or a different aircraft type.
Allegiant Air A319 Seat Map
The Airbus A319 is Allegiant’s smaller aircraft, configured with 156 seats in a 3-3 layout across 26 rows. Seat pitch is 30 inches throughout — slightly more consistent than the A320 variants. There is no Allegiant Extra option on the A319. The entire cabin is single-class economy.
Exit row seats are at Row 12 on the A319, offering the only meaningful legroom upgrade on this aircraft. Row 12 exit row seats have extra legroom but no under-seat storage during takeoff and landing, and the tray table is in the armrest rather than the seatback, which makes the seat slightly narrower than standard. Whether that tradeoff is worth it depends on your height.
Allegiant Seat Dimensions: What the Numbers Mean
| Measurement | Standard Seats | Allegiant Extra (A320 180M) |
| Pitch (front to back) | 28–30 inches | ~34 inches |
| Width (seat) | ~17–18 inches (standard 3-3 Airbus) | Same width, more legroom |
| Recline | None — fixed slimline seats | None |
| Tray table | Small, seatback-mounted | Larger |
| Seatback screen | None | None |
| USB power | A319/A320: varies by aircraft; 737 MAX 8: yes (USB-A and USB-C) | — |
Seat pitch is the primary comfort variable on Allegiant. At 28–30 inches, standard Allegiant seats are on the tighter end for domestic coach — comparable to other ultra-low-cost carriers like Frontier and Spirit. The slimline leather seats don’t recline, which means the person in front of you also can’t recline into your space, partially offsetting the tighter pitch. Several passenger reviews note the back support on Allegiant’s slimline seats feels better than expected for a ULCC.
Best Seats to Choose on Allegiant Air
For Maximum Legroom (Free Options)
- Exit row seats: Row 12 on A319; exit rows vary by A320 configuration — check the seat map. These are the only free legroom upgrade on Allegiant when not blocked for purchase
- Bulkhead rows: The first rows behind any cabin divider or galley area often have more floor space, though the tray table may be in the armrest rather than the seatback
Worth Paying For
- Allegiant Extra (Rows 1–5 on 180-seat A320): At $20–$51 depending on route, the 34-inch pitch is a meaningful upgrade for passengers over 5’10” or anyone on a longer flight
- Allegiant Extra bundle: Includes the legroom seat plus priority boarding and reserved overhead bin — useful on full flights where overhead space fills quickly
Seats to Avoid
- Last row (Row 31 on 186-seat A320 / back rows generally): Proximity to lavatories is the main drawback; passenger reviews specifically flag this on the A320
- Middle seats in the back rows: Limited overhead bin access once boarding is complete, and last off the plane
- Exit rows if you can’t assist in an emergency: FAA regulations require exit row passengers to be able to assist in an evacuation — if this doesn’t apply to you or members of your party, request reassignment at the gate
What Allegiant’s Seats Don’t Have
Setting expectations before booking:
- No WiFi: As of early 2026, no Allegiant aircraft has in-flight WiFi. The airline has stated WiFi is planned but has not announced a vendor or implementation timeline. Bring downloaded content
- No seatback entertainment: No screens on any seat on any Allegiant aircraft
- No seat recline: All standard Allegiant seats are fixed slimline seats — they don’t recline
- USB power: Available on Boeing 737 MAX 8 aircraft (USB-A and USB-C at every seat). Availability on A319 and A320 varies — some aircraft have been retrofitted with USB ports, others haven’t. Don’t rely on power being available unless you’re confirmed on a 737 MAX 8
The practical preparation: charge your devices fully before the flight, download entertainment ahead of time, and don’t plan to work on a laptop using the tray table (it’s small and not sturdy enough for a laptop in most reviews).
Aircraft Swap Warning
Allegiant is known for aircraft swaps — substituting a different aircraft type or configuration than the one you booked. This matters most if you’ve paid for Allegiant Extra seats: if your 180-seat A320 gets swapped to a 186-seat configuration, those rows 1–5 may simply not exist on the replacement aircraft. Allegiant’s policy on refunds for lost Allegiant Extra seats in a swap varies. Checking your booking in the days before departure and monitoring for configuration changes is advisable if you’ve paid for a specific seat upgrade.
How to Check Your Specific Seat Map
The seat map for your specific flight is visible at booking on allegiantair.com — select your seats during checkout and the map will show which configuration is scheduled. For the most detail on specific seat pros and cons (window alignment, lavatory proximity, exit row mechanics), SeatLink and seatmaps.com both carry updated Allegiant seat maps with passenger reviews per seat.
Frequently Asked Questions
What is the seat configuration on Allegiant Air?
All Allegiant aircraft use a 3-3 seat configuration (three seats on each side of the aisle). The A319 has 156 seats, the A320 has either 186 seats (older, all-standard) or 180 seats (newer, with Allegiant Extra rows 1–5). The Boeing 737 MAX 8 has around 190 seats.
Does Allegiant have extra legroom seats?
Yes — on the 180-seat A320 configuration only. Rows 1–5 are designated Allegiant Extra (also called Legroom+), with approximately 34 inches of pitch versus 28–30 inches in standard rows. This option is not available on the A319 or the older 186-seat A320.
Do Allegiant seats recline?
No. All standard Allegiant seats are fixed slimline seats with no recline. This applies to both A319 and A320 configurations.
Does Allegiant Air have WiFi?
No — as of early 2026, no Allegiant aircraft has in-flight WiFi. Download content before your flight.

Final Thoughts
Allegiant’s seating is exactly what you’d expect from an ultra-low-cost carrier: functional, no-frills, and designed around short leisure routes where passengers are primarily price-sensitive. The Allegiant Extra upgrade is a genuine improvement for taller passengers or those on routes long enough to make the pitch difference meaningful — but only on the 180-seat A320, and only if the aircraft doesn’t get swapped before departure. Checking the seat map at booking and confirming the configuration in the days before your flight are the two practical steps that make the most difference in managing your Allegiant seating experience.
