MH RTW fares are definitely loaded into the CRS ex MLE and CMB. I am perplexed why they will not ticket it.
The cost in USD for the 3 grades (30k/35k/40k) ex MLE are:
$2747
$3041
$3494
For business class:
$6036
$6949
$8151
This comes from Expert Flyer, which comes from Sabre. Perhaps you need to find a local agent who uses Sabre, and then have them press MH directly?
