I booked everything through Qantas, including the non-refundable hotel and flights through DFW, outbound and return.
Now this was originally 25/8 - 8/9, and then elderly parent's health took a turn, and deteriorated quickly.
Qantas rebooked my flight easily enough, and even worked out rebooking the hotel without penalties.
Of course the outbound flight was late, and I missed my connection, but they already moved me to the next available.
The hotel had my booking dates correct, but there were still issues. Luckily the night clerk was quick to resolve whatever issue Qantas had left outstanding with Expedia.
All good, then, until I got to the airport to start my return journey. Something in the DFW-Sydney booking didn't match what TSA had online.
Spent nearly an hour going back and forth between check-in and security.
Qantas customer service is 9-5 M-F and 14 hours into tomorrow, and I couldn't find a phone number anyway.
TSA eventually agreed to let me through, but only with magnametor, full body scan, and full pat-down.
