Allegiant Airseat guide: economy legroom, best seats & upgrades
Allegiant Air economy seats pitch from 28–30 in on narrowbody jets up to 29 in on widebody routes. Exit rows often unlock more space for free. Here is exactly what to book — and what to skip.
How much legroom does Allegiant Air economy have?
Every Allegiant Air aircraft carries a slightly different economy layout. The table below shows pitch, width, seat configuration, and the routes each aircraft type flies most often.
| Aircraft | Economy pitch | Width | Layout | Routes |
|---|---|---|---|---|
| Airbus A320 (180-seat, Allegiant Extra config) | 28–30 in | 17 in | 3-3 | Primary domestic leisure routes nationwide; select sun/beach destinations; ~70% of A320 fleet retrofitted by 2026 |
| Airbus A320 (186-seat, dense standard) | 28–30 in | 17 in | 3-3 | Domestic leisure routes; older configuration being gradually replaced by 180-seat Allegiant Extra variant |
| Airbus A319 (156-seat) | 29–30 in | 17 in | 3-3 | Shorter domestic routes; thinner leisure markets from secondary cities; fleet of ~7–15 aircraft |
| Boeing 737 MAX 8-200 (190-seat) | 29 in | 17 in | 3-3 | Growing domestic network; entered Allegiant service September 2024; projected ~20% of ASKs by end of 2026; 16+ aircraft in fleet |
Premium-cabin pitch varies by aircraft. See the upgrade section below for exact figures.
What are the best seats on Allegiant Air?
On 737 MAX 8 and Allegiant Extra-equipped A320s, choose rows 2A or 2F in Allegiant Extra for 34–35 inches of pitch without the Row 1 tray-table-in-armrest drawback. On standard A319 and A320 aircraft, exit rows (Row 12 on A319; rows 12–14 on A320) deliver 4–6 extra inches of legroom at low or no cost at check-in — the best value upgrade on a no-recline, no-entertainment fleet.
General rules that apply on any Allegiant Air flight
- Exit rows — typically 4–8 extra inches of pitch with no seat in front. Often free to select at check-in even when they cost money at booking.
- Bulkhead rows — the most forward-cabin legroom, but tray tables live in the armrest and overhead bins may be pre-assigned to another cabin.
- Window seat for sleep — a wall to lean against and no one climbing past you. Rows near the middle of the plane minimize wing noise and turbulence.
Which Allegiant Air seats should I avoid?
Last rows on all aircraft (proximity to lavatories, often no window, slightly narrower fuselage). Row 1 middle seats (1B, 1E) have tray tables in armrests making effective seat width narrower. Rows adjacent to overwing exit doors (e.g., row 11 on A320) can experience cold drafts. Middle seats (B and E columns) throughout the cabin are particularly uncomfortable given no recline, no seatback screens, and no power outlets on A319/A320.
How to upgrade your Allegiant Air seat
Allegiant Air offers 3 cabin tiers above standard economy. Prices below are typical ranges — exact costs shift with route length, demand, and how far in advance you buy.
| Cabin / product | Pitch | Typical price | What's included |
|---|---|---|---|
| Allegiant Extra (A320 Allegiant Extra config) | ~34 in | $20–$51 above base fare per segment | Priority boarding, reserved overhead bin space, complimentary drink, upgraded leather seats with larger tray tables; rows 1–5 |
| Allegiant Extra (Boeing 737 MAX 8) | 35 in | $20–$51 above base fare per segment | Priority boarding, reserved overhead bin space, complimentary drink, USB-A and USB-C charging at every seat; 21 designated seats |
| Exit Row / Legroom+ seats | 34 in (varies by aircraft/row) | $30–$35 per segment | Extra legroom only; no additional amenities; requires ability to assist in emergency evacuation; no under-seat stowage during takeoff/landing |
On most Allegiant Airroutes, upgrading at check-in or bidding through the airline's upgrade program costs less than buying at booking.
How much does seat selection cost on Allegiant Air?
$10–$19 per segment for standard economy seats (varies by row and route); $30–$35 per segment for exit row (Legroom+) seats; $20–$51 per segment for Allegiant Extra. Skipping seat selection results in a free random assignment at check-in with no guarantee of sitting with travel companions. Official disclosed range: $0–$80.
Basic economy rule
Allegiant does not use a "basic economy" fare tier. All tickets are standard economy. Seat selection is an optional paid add-on at booking. Passengers who skip it receive a random seat assignment at check-in at no charge; groups and families are not guaranteed to sit together without paying the seat selection fee.
