We're booked on Celebrity Millenium for 15SEP Transpacific cruise in Aquaclass. This was a rollover from the SEP'22 cruise that was cancelled by Celebrity. I heard from Celebrity this cruise is crazy oversold, but no other information or change options were offered. I've been trying to make my full payment while still able to get full refund in case I have cancel, but the page has been unavailable for over a week. Another issue is I booked the incorrect date for my return trip from TYO. The cruise was rebooked in APR'22 so airspace was not available to book. I used the app (that Celebrity always pushes you to) and the dates posted (still) are 15-29SEP on the first two pages of the cruise display. The actual end date is 30SEP. Called my cruise planner who advised, per the invoice, the cruise dates have always been 15-30SEP. Issue is I booked my air the day the flight rolled into the system (4ONV22), based on the dates I saw in the app (15-29SEP). Two seats on JAL in business for an insanely low amount of miles; I was booked got great deals and was happy! Now, I would have to suffer on AA at 450k miles pp. I sent a screen shot to the rep stating, due to errors in the display, CEL needs to get me home and she said she'd see what she can do - that was three weeks ago. (I believe the issue is in their code - the pages on the app shown first do not consider the date change from the Int'l Date Line. Code is reading start date of cruise + cruise length (15SEP+14 days=29SEP when it needs to add a day when travelling westbound of the Dateline which whould show the 30th. The main code considers this.) Not my job to verify dates in all different locations to ensure their code is correct! Anyway, will call to see if I can pay in full and see if any options are provided. Anyone have suggestions on how to handle? i agree that Celebrity is acting really wonky with these bookings - not their usual standard at all.
