All pilots start out by building their hours with smaller aircraft. If you want to become a Delta pilot one day , best advice is to start flight training at a school affiliated with the Delta Propel program. Yes Delta will still be flying the a350's well into the 2030s.
@@ColdAVI i work for Delta so im biased lol but i wouldn't say becoming a pilot for either one is "harder" than the other. both airlines are likely going to be retiring their 757s and 767s in the next few years, unfortunately.
