Crew is great. Required early boarding and the staff was very accommodating. Seats are narrow and cramped. Not even enough room to get out of window seat to aisle easily. I am not a large person 5’4 135lbs. Small sandwich rather than awful snacks would be appreciated since there is not a lot of connection time provided and long lines at food vendors. Since ticket costs have sky rocked adding $5 to the ticket for a sandwich would nit even be questioned
