We will be flying LAX to JFK with our 20 lb. Corgi, Lucy, in an airline approved, soft-sided Sherpa carrier. The plane has only a 4 row business and the rest of the seats are coach. Last time we flew with Lucy we were in the 1st of the 4 rows of business class and there was no seat in front of us to store Lucy and her carrier. There were also no other seats in business with room in front to store a carrier because they changed the seats to recline, leaving less than 3" of space under the seat in front. The flight attendants had the right to move Lucy & carrier behind the 4th row seats, and threatened many times to do it. Has anyone had experience flying a dog on Delta in the business class rows # 1-4, or coach?
