Attaching objects to spline HELP PLEASE

hey there
I am familiar with unreals basics as in creating a world ect… but i am a noob at blueprint stuff
I have a flying horse (Pegasus if you will) and its been animated flying and i just want to attach that asset to the spline but i dont know how
I found a tutorial which uses ITween but we dont have that
can anyone explain how to do it without using that plugin
