Hawaii appears to becoming the 1st location of exclusively Delta A321-neo aircraft. Currently there are two
routes are still in play for the efficient frames: SEA-HNL (2 daily B757-200 flights) and LAX-HNL (2 daily
B757-300 flights). These 2 routes have been having the A330-900-neo planes swapped in, but are not the
full time aircraft usages. LAX-LIH is scheduled to begin A321-neo service early next year (2023-Jan-20), again
replacing the aging B757-200 aircraft. That being said, Where might the next destinations to have the A321-neo
aircraft inserted? Maybe the Caribbean destinations, which are ALL within the range of Deltas A321-neo a/c.
Currently there are 9, most of the routes are run with B757-200 aircraft and a couple are using B737-800 a/c.
The swap from 738s to 32Ns would render a 20% increase in seating and 752s to 32Ns are pretty much a 1
for 1 swap. Another thought might be the Central American destinations (BZE and PTY) being flown currently
with B737 a/c. A third group might be South American destinations (BOG and UIO) being flown currently with
752s. All of the above destinations are still within the range of Delta's current A321-neo aircraft. Delta does
have one rather short Atlantic destination, KEF being flown by single isle 752 aircraft and still within range
of the 32Ns. A last set if destinations would then encompass the east coast to Europe routes, Some within
the range of Deltas current 32Ns, and some would need the LONGER or EXTENDED range verions - which
I do not believe DL has on order, but that's not to say they won't in the future. Most of the European flights
are being flown with the wide bodied twin isle B767-300ER aircraft (which) DL says they would like to retire.
A distance of 7+ Hours across an ocean (like the Atlantic), most passengers would not like going along with.
That being said, the usage of the single isle A321-neos across the Atlantic is a very long shot to happen. Let
us know what your thoughts are on this matter.
