Same thing is happening on the 320 fleet, 1 acft is always out of service getting retrofitted with winglets on the 12/120 configured aircraft. These are being retrofitted in LIS. Also, the 330 fleet is getting repainted and hence 1 330 is always out of service and in DUB. this has been going on the last 6 months or so and will continue for the next few months too. This is why the 350 delays are having so much impact as the planned long term maintenance has to occur.
