Economy Class
Allegiant Air's A320 is configured exclusively as Economy with 186 seats in a dense 3-3 layout. The 28-inch pitch is at the lower end of the industry standard for domestic and short-haul flying — it suits flights under 3 hours but can feel cramped on longer routes. Seat width is 18 inches, which is narrow even by economy standards and leaves little armrest relief for larger passengers. The aircraft carries no seatback entertainment system; passengers must rely on personal devices, streaming subscriptions, or the airline's content offerings if available. There are no lie-flat beds, reclining seats, or premium cabin upgrades on this aircraft type. Allegiant operates this A320 as a true low-cost carrier product: expect amenities to be minimal, beverage and food service to be basic and paid, and the cabin to feel packed on peak-load flights. Before booking, verify the specific row positions of exit rows, galleys, and lavatories on Allegiant Air's official seat map, as those zones carry noise and service interruptions that degrade comfort on Economy-only narrow-bodies.
Best seats
| Seat | Cabin | Why |
|---|
| Forward window seats (rows 1–10, positions A or F) | Economy | Early deplaning, slightly more legroom perception due to bulkhead distance, and fewer passengers walking past during flight |
| Aisle seats, mid-cabin (rows 11–25) | Economy | Unrestricted legroom for tall passengers and easier lavatory access without disturbing seat neighbors |
| Window seats, mid-cabin (rows 11–25) | Economy | Ability to lean against the fuselage for rest without middle-seat crowding |
Seats to avoid
| Seat | Cabin | Why |
|---|
| Middle seats throughout (position D) | Economy | Squeezed between two passengers with no aisle or window escape; armrest conflicts are inevitable on a narrow 18-inch-wide Economy cabin |
| Rear rows near galley and lavatories | Economy | Odor, noise from lavatory flushing and service carts, and constant foot traffic disrupt sleep and comfort |
| Exit rows (if available and blocked from recline) | Economy | Verify on the seat map — some airlines lock exit-row seats from reclining, eliminating your only posture relief on a 28-inch pitch |
Economy Cabin
Allegiant Air's A320 is configured entirely in a single-class economy layout with 186 seats in a 3-3 configuration across the fuselage. This is a no-frills, high-density setup typical of ultra-low-cost carriers operating on point-to-point routes. All passengers share the same cabin environment, seat type, and amenities level.

Seat Selection & Layout
The 3-3 configuration means three seats on each side of the center aisle. Window and middle seats are grouped together (A/B/C on the left, D/E/F on the right). There are no premium economy or business-class products on this aircraft—all 186 seats are standard economy.
Allegiant Air offers seat selection during booking and check-in. Preferred seating (typically front rows, exit rows, or extra-legroom rows, where available) carries an additional fee. The airline also sells bundled packages that may include a seat selection along with baggage allowance. Specific fee amounts vary by route, season, and booking date; check Allegiant Air's website at the time you book to confirm current pricing and which rows qualify as premium or standard.
Aisle seats are popular for bathroom access and quick deplaning. Window seats appeal to passengers who want to lean against the fuselage for sleep. Middle seats are the least desirable and often go unsold or sell at a discount. On a full flight, expect the cabin to feel busy, especially during boarding and exit.
💰 True Cost Breakdown
Allegiant Air, as an ultra-low-cost carrier, operates on an à la carte pricing model. Seats are typically organized into fare zones: front-cabin rows (closer to the cockpit and exit), exit-row seats (where available on this aircraft), and standard economy rows. Each zone carries a different selection fee, with front and exit rows commanding premium prices.
On an A320 with 186 economy seats in a single cabin, priority selection benefits passengers traveling as pairs (window or aisle plus middle) in the front cabin, as those rows deplete quickly. Exit-row seats, if available, offer extra legroom but also carry flight-safety responsibilities.
Whether a seat fee is worthwhile depends on your trip length, personal comfort preferences, and how much you value guaranteed seating location. For short routes (under 2 hours), a standard seat may suffice. For longer routes or if you are tall or have mobility concerns, a front-cabin or exit-row seat can improve the experience. Allegiant Air does not charge explicitly for not selecting a seat—the airline assigns you one free at check-in, though your choice may be limited. Check the airline's website before booking to see current zone pricing and row assignments for your specific flight.
📐 Space Reality
Allegiant Air's A320 offers 28 inches of pitch and 18 inches of seat width. For context, pitch is the distance from one seat back to the next seat back; width is the distance between the armrests.
A 28-inch pitch means roughly 28 inches of fore-aft space from the back of the seat in front of you to the back of your own seat. For an average adult (around 5'8" to 5'10"), this leaves about 2–3 inches of legroom when you sit upright with the seat in front unreclined. If the person in front reclines, your legroom shrinks further. This is tight for longer flights and especially tight if you have long legs, broad shoulders, or need to move around frequently.
An 18-inch seat width is narrow. The standard width on many traditional carriers is 17–18 inches, so Allegiant Air is not unusually tight by number alone. However, passengers report that narrow cabins with minimal padding on the seat cushion amplify the sensation of width constraints, especially on cross-country or 3+ hour routes. If you are broad-shouldered or larger-framed, the 18-inch width—combined with 28-inch pitch—makes the seat feel more confining than the specs alone suggest.
Compared to a direct competitor such as Spirit Airlines (which also operates A320s on similar ultra-low-cost routes), Allegiant Air's A320 cabin is functionally equivalent. Both carriers prioritize density, and both offer similarly constrained pitch and width. The real-world comfort difference between airlines of this category depends more on seat condition, maintenance, passenger load, and cabin temperature than on the nominal measurements.
Honest assessment: on flights under 90 minutes, most passengers tolerate 28-inch pitch. On flights of 2–3 hours or longer, frequent flyers and taller passengers often report that the space feels cramped by the final hour. Bringing a neck pillow, wearing compression socks, and standing in the aisle every 30–45 minutes can help. If you are over 6 feet tall, consider paying for a front-cabin or exit-row seat to maximize your legroom.
⚡ Power & Connectivity
Allegiant Air's A320 does not include in-seat USB power or AC power outlets as standard amenities on economy seats. There is no built-in seatback inflight entertainment system or WiFi service advertised as a standard feature on the A320 fleet.
For on-board entertainment, most passengers bring personal devices (phones, tablets, laptops). If WiFi is available on your flight, check Allegiant Air's website or contact the airline ahead of time to confirm availability and any associated costs, as services change and vary by aircraft and route.
For flights on the A320, which are typically 1–4 hours depending on route, a fully charged phone and downloaded entertainment (music, videos, podcasts, e-books) are essential. If you plan to use a laptop, work in spreadsheets, or stream content, bring a power bank with sufficient capacity (at least 10,000 mAh) to keep your devices topped up for the flight duration and any delays. This is prudent general advice for ultra-low-cost carriers, which rarely provide onboard power.
🏃 Boarding & Exit Strategy
Allegiant Air typically boards by zones or groups, with priority reserved for passengers holding higher-tier loyalty status, passengers with large carry-on baggage, and those occupying front-cabin rows. The airline may also offer priority boarding as an add-on fee at the time of booking or check-in.
If you are in an aisle seat in the front third of the cabin and board early, you will deplane quickly—you can stand up immediately and walk toward the exit without waiting for middle and window-seat passengers to gather belongings and move past you. Window and middle-seat passengers typically deplane slower, as they must wait for aisle traffic to clear before they can stand.
On turnarounds (quick ground stops where the aircraft refuels and rebooks passengers for the next flight), some aircraft use a rear-door exit to speed the outflow. Allegiant Air does employ rear-door exits at certain airports as an efficiency measure. If you are in a rear aisle seat (near the back of the cabin), you may benefit from a rear-door exit if it is used on your flight—you would deplane without walking the full length of the aisle. However, not all airports are equipped for rear-door operations, and Allegiant Air does not guarantee rear-door use on any specific flight. Check with the flight attendants or gate agent for exit procedures before your flight.
Bottom line: if fast deplaning matters to you, book an aisle seat in the front cabin and board as early as your fare class permits. Avoid middle and back seats if you want to avoid a long queue to the exit. For boarding requirements and current priority policies, visit Allegiant Air's website or contact the airline directly, as these policies can change seasonally and by route.
