Ok so bit of a tale of my saga with needing changes for my OWA in July/Aug 2023.
Needed to make one change fly from Brussels to New York via Heathrow rather than Budapest and also requested that my Helsinki to Prague flight was moved forward a day. All flights were there and available so no issues.
Called day 1, Kat in Fiji tried to help, got new flights on the booking but old flights still there, kept going to support and putting me on hold. Seemed to give up and said she would call back in an hour and never did.
Called day 2, Darryl from Philippines seemed to get rid of the unwanted flights, ensure new flights were booked but couldn't get taxes worked out and seemed to be an issue if there were extra points (he said his system had crashed). Took my credit card details for extra taxes, said he would call back if there were issues but seemed to think all was ok. Sent through a confirmation to appease me from amadeus.
Day 3 no credit card charge and tickets still showing old flights (while the booking showed updated ones), got worried so called up. Got Sarah? from Philippines, mentioned Darryl, she seemed to know him and possibly messaging him while I was on phone and on hold. Tried to escalate in ticketing and also mentioned Darryl had done twice to prioritise. Guaranteed they would be ticketed in next 24 hours...
Day 4 (very early in morning) got new ticket emailed... Hurray
Day 4 mid morning to my surprise Darryl called and said everything was sorted and asked if he could assist any more.
In general found everyone very helpful but some (Kat from Fiji) in this case may have been lacking a bit of knowledge. They also seemed to know about issues with tickets being lost from not being reticketed and were happy as a result to try and escalate.
Overall I found that if you are nice, polite, ask them their name and how their day is going they were always willing to help and to be honest shocked. I can only imagine some of the abuse they cop...
