IME to say that their customer-facing online systems are "primitive" would be a vast overstatement.
Everything from
booking to viewing your reservation (as you've found out) to online check-in to flight information is broken, inconsistent, incomplete, incorrect, or some or all of the above.
And it took me a mere 8 segments in 2 months to encounter problems with all of this.
I wish they were using abacuses. The new CEO should equip everyone with them.
They do have lovely customer-centric employees and good onboard service, though, but no IT skills. And since their PSS is SITA's (one of the weakest out there), no other website that I know of other than MH's broken one will display your record.
