Yes that's true they need the aircrafts ASAP.
But, It will be a total shock if they do order the B717 because it has been stated by 5J
itself that the B717 has an uncertain future and it doesn't want a fleet of B717 that might not be in production in the next couple of years.
The reason 5J
wants a new fleet is to further shoot itself in front of Philippine Airlines. Currently PR
's 733, A320, as well as A330's, plow the skies in the Philippines, and the public in the Philippines is quiet influential with regards to the "brand new ness " of aircrafts.
therefore if 5J
orders B717, and the production line ceases for example... PR
Can put a campaign blitz that it still has Brand new planes... Or planes that are still produced. Cause the public wont know that the B717 would be new.
anyways that's just Filipino mentality about new stuff. I cant really explain it, but some of our Filipino friends might vouch for me on this one.
Now if Boeing gives 5J
a really SWEAT deal, that if lets say they do cease production, and it can swap them for B73X series, then YES we might see a B717 deal, but nothing less.
Embraer might be out of question because of availability like you guys have stated.
A318 would be too heavy but can be a possibility. The A319, yes might be overcapacity for 5J
, BUT provides underbelly containers which might increase cargo, since they have agreements with many shipping companies such as aboitz.
