From "MH370 Data Communication Logs.pdf"
Page 36:

Page 37:
7/03/2014 18:04:29.413 IOR-P10500-0-3859 IOR 305 10 P-Channel TX 0x61 - Request for Acknowledge (RQA) User Data

18:05:11 - Data-2 Ground to Air transmission, automatic ACARS retransmission after expiry of 90 sec timer. Terminal is not responding.



IMHO, this indicates that ACARS transited by SATCOM. At least some of them. From the comments, these ACARS are about "AIR DATA-2". From memory, these data contains ??? and fuel remaining at 17:07 (all the contents had not been published).
