Dear Flyertalkers,

I was unable to find an answer in previous threads, so I ask your expert advice.

I need to change the date of an upcoming flight with BA (booked using CX miles) to one day later. Flight is available with same routing & flight numbers, only date change.

Does this require a ticket re-issue (or not) for a date change? I ask because when I purchased the flight a few months back, it was 90'000 miles and now is 115,000 miles.

My very best and thanks for your help.
