Sherpa Original Deluxe (Large) — dimensions & which airlines it fits
Sherpa Original Deluxe (Large): 19 × 11.75 × 11.5 in external, up to ~22 lb. Larger dog size. At 19 × 11.75 × 11.5 in it is over every published under-seat limit we track — including the roomiest 11-inch ones (Delta, American, United), which it exceeds on all three dimensions. Size down to fly; this one is for the car and the house.
It clears 2 of 58 airlines with a published limit outright. Check your pet before you buy. This one is rated up to ~22 lb — and Sherpa's own limit is 18 in long × 10.5 in tall. Same bag, other sizes: Small up to ~8 lb (fits 41) · Medium up to ~16 lb (fits 11). Clears more airlines: the Small clears 41 of 58, but takes a pet only up to 13 in long × 7.5 in tall — check yours against that before switching.
Weight alone under-determines fit — a pet can be under the weight limit and still be too long. Measure your pet lying down and compare against both. How to measure →

The airline decides whether the bag fits. Your pet's weight decides whether the size is right — and those two can point at different Sherpa models. Check the pet first: how to measure →
