I'm assuming you're connecting to HKG?

Yes, that is correct.

Same day standby is permitted for domestic itineraries. The agent was correct in regards to an international journey. Can you phone and change the flight? If you are booked as DCA-HKG as a single sector , it should require a reissue to make it into 2 sectors

But SDC doesn't include ticket reissue.

Do the flights actually depart on the same calendar day? AA uses calendar days for SDFC rather than the 6:00 am - 6:00 am they use elsewhere, meaning, for example, that you can't change from a 12:05 am flight to one ten minutes earlier.

I want to attempt a same day confirmed flight change to get from New York to San Diego. My existing ticket is LGA-ORD-SAN. I want to try and change to a nonstop LGA-SAN if possible (recognizing there will be some agent discretion changing from a connecting to a nonstop).

For this purpose will LGA and JFK count as the same origin? Is there anything else to think of?

There's no LGA-SAN nonstop... IME I've been able to switch between LGA and JFK without a problem.

D'oh. I meant JFK - SAN. Thanks for the tip, I'm going to try.

Only if the segments were separate. Mine was all through flight in I class. There's no I-class in DCA-DFW.

Thankfully I managed to ask to agent to re-issue that in AC after a sudden update of the Northeast weather waiver.

SDFC Question
 

Hello all

I am a recent UA convert and I recently booked a first class flight on AA.com. During the booking process I noticed that if you hovered over the "First" button on the booking pages it lists "Same-day flight change (subject to flight availability)" as a benefit of being in first class. I know this is a little at odds with what was known for SDFC, but with the recent changes I figured it was a new change. The kicker for this was that my fare rules specifically state (fare basis: OA14USI5/WAUP):

"PASSENGERS WHO PURCHASED TICKETS FOR FIRST OR BUSINESS OR COACH CLASS BOOKED IN Y/D/I/J/A/P/F INVENTORIES MAY USE SAME DAY FLIGHT CHANGE WITHOUT CHARGE AS NOTED BELOW"

So today I had to actually change my flight. Online it let me change for free but did not have the flights I wanted so I called in. First agent didn't think this was doable so I HUCA. Second agent didn't seem to have an issue and rebooked me (even switched coterminals BWI->DCA). After four hours, the ticket still hadn't reissued. So I called again and after going back and forth with the agent and rate desk for over an hour they refused to allow me to change the ticket and were trying to get me to pay any fare differences. I was kind of fed up at this point so I just cancelled the ticket (which was non refundable). I have the luxury of not needing to go on this trip and I was just fed up after more than 3 hours on the phone today.

Am I missing something here? Why would the fare rules say that you could use "same day flight change" regardless of class (negating any possibilities of wonkiness from the WAUP) and essentially no agents agree with that - yet alone even acknowledge that that line existed for my ticket?

I have a flight on AA coming back that I booked with my Avios points so it comes out of the MileSAAver fare bucket. There is an earlier flight in the day that has availability, but I wasn't sure I would make it in time (finishing a tour the same day). So does that mean that if there is still MileSAAver availability on the day of travel I can attempt to do a SDC on it without fees?

On an award ticket you'd have two options: try to change the ticket itself with the issuer (BA?), or try for SDC with AA.

Thanks!

How does SDC work with the merged program? Namely, may I make a SDC on a US codeshare flight when ticketed on AA stock?
