Cabin guide
Economy to first — what to actually expect.
A plain-language reference for Pioneer Valley flyers booking through the almanac.
Economy / Main
The default cabin on every domestic route the almanac tracks. Pitch is typically 30–31 inches; carry-on policy varies by carrier and fare bucket.
Premium economy / Comfort+
An extra-legroom cabin on JetBlue (Even More Space), Delta (Comfort+), Icelandair Comfort, and Aer Lingus Plus. Worth the upgrade on transatlantic redeyes; rarely needed on snowbird flights.
Business
Lie-flat seating on the Boston transatlantic routes — JetBlue Mint to London, Aer Lingus Business to Dublin, Delta One to Paris. Fare multiplier on the almanac is roughly 3.6×.
First
Mostly a domestic distinction on Delta and American shuttles into DCA/LAX. The cabin is real but small; recline and meal upgrade are the main benefits.
