I had a long flight last weekend from RKSI to KLAX about 11 hours flight.
LA Center was online and also the Tower.
While I was approaching the coverage of LA Center, I contacted him as below
P: LA Center good day, KAL0000 with you. FL 370.
I was about a few miles away from TILT and then he said something but I could only understand partially. I should've asked him again to make sure but there was much traffic so I missed my chances.
The words I heard was something like " Intercept TILT ------(I guess decent by WURLL) WURLL, DIRBY1 Arrival"
I read back what I heard(partially) and I could move on but the problem was, when I requested him, permission to decent, he said he already gave me the instruction.
Does anyone have an idea what the LA Center was trying to say? I am quite new to VATSIM I need some help.
