You can HUCA, but when I look at matrix.itasoftware,com with only MAD, HEL, DOH, AMM showing as valid routings I only see HEL and DOH as options on the results page. If they won't reroute you after escalation, then will they offer full refund so you can just book it yourself? Not sure what you paid, but QR in J is coming in at $3348. AY is over $10K!
