I know the A320 remodel will come but I will give a list of A320 Veriants NEO will be included. Update: I will still include the A319 and A320 with CFM without winglets as I want to cover every single aircraft which will hopefully get remodeled as well as changing the picture of A320 CFM with winglets, A320 IAE and A320 IAE with winglets to a better quality picture.

Of course the A320NEO engines PW and CFM has a similar shape so it won’t be added.
