I think there might have been some delays. I recently saw the fleet plan documents and I'm pretty sure it showed deliveries thru 2028. Maybe those are the XLRs, i just don't know.
Either way, when we hit our fleet plan of 215 we should have about 3250 pilots or so. Currently we have about 1440 pilots, so I suspect we will hire 1900+ pilots between now and 2028 accounting for retirement and attrition. That's a manageable amount of hiring.
