Not only have I never had a problem with the Airbus, but I love them. In my experience they are reliable, and for a single-aisle plane spectacularly comfortable on coach, particularly in the Economy Plus section. I eagerly scan the new timetable every month just in case the tired 737 has been replaced by the A320 on the IAD-LGA route (they make the change about twice a year - and I love those 2 month periods
).
