Seat dimensions
Not published. Greyhound's official pages describe 'comfortable leather seats', 'ample legroom', and 'everyone gets a window or an aisle seat' but give no seat-width measurement.
| Equipment | Class | Width | Source |
|---|---|---|---|
| Prevost X3-45 / MCI D4505 (typical fleet coaches) | Coach | Not published | community reports, undated approx. 18 (community measurement, cushion width; not official) |
Verification notes (seat dimensions)
Official onboard page (greyhound.com/travel-info/onboard) publishes no width figure; secondary blogs cite 17.5-18 in but are undated content-farm sources, so only the forum measurement is recorded. Fleet is largely MCI D4505 and Prevost X3-45 coaches in 2x2 layout, all seats window or aisle (no middle seats).
Seatbelts
Official Bus Features page: 'All of our new buses have three-point safety belts (that's most of our fleet)' — shoulder and lap harnesses, usable with standard child car seats. Older coaches may lack belts. per Greyhound Lines, pending our direct verification
Verification notes (seatbelts)
Belt length is not published. Wording 'most of our fleet' means belt availability is not guaranteed on every departure. Secondary trade press (metro-magazine.com) reports Greyhound began equipping its fleet with seat belts in 2009.
Seatbelt extender
Not published by the operator. per Greyhound Lines (verified 2026-06-13)
Verification notes (extender)
No official Greyhound page found that mentions seat-belt extenders, belt length, or personal extender rules. Outreach required.
Second-seat policy: “No named customer-of-size policy; 'reserve the seat next to you' option”
Greyhound publishes no customer-of-size rule and no requirement for larger passengers to buy a second seat. Its Seat Reservations page offers the ability to 'reserve the seat next to you if you need additional room' for a route-dependent fee.
When a second seat applies
Not published — no official trigger (e.g., armrest test) found.
How to arrange it
During initial booking only: when adding the passenger to the booking you can reserve the adjacent seat (fee varies by route, schedule, booking time, and seat category). Seats cannot be added or changed after the ticket is booked. A secondary report (mightytravels.com, Oct 2024) describes a 'Neighbor-free' option with the second seat at a 45% discount; this figure is not confirmed on greyhound.com, so the tighter official reading (route-dependent fee, no stated discount) leads.
Refunds
Seat reservation can be cancelled up to 15 minutes before departure; refund is issued as a voucher (per official Seat Reservations page).

Verification notes (policy)
Secondary 45% second-seat discount claim: https://www.mightytravels.com/2024/10/greyhounds-reserved-seating-policy-a-step-towards-better-bus-travel/ (type: secondary, accessed 2026-06-13, published 2024-10, confidence: secondary). Same source notes onboard enforcement of assigned seating is inconsistent. Armrest design between seat pairs is not documented officially. Greyhound is owned by Flix; booking flows mirror FlixBus.
