ST E+ benefits on CO, DL
 

I am a Lying Poo Gold on KL, and will be travelling to the US and need/want to fly on CO & DL, doing some MR's, while indulging my hobby of Cloud Photography.

I would like to know how CO & DL are likely to treat me if I want to make Same Day Changes.

DL apparently allows its Gold members to do so FOC, waiving the $50 fee.
But do they do for other ST E+ ?

Having had a quick search on the CO board, cannot find the answers to that.
Thanks for your help ?

CO allows standby for same day flights for free, unless it's recently changed. DL has let me once change without a fee, though it was from my 3 hour delayed flight to the earlier one that was also 3 hours delayed. She tried to charge me the fee, I was in the club room, stated I was gold on NW and that it wasn't my fault that the flights were late. Normally, they'll charge you.

DL will charge you for a change unless you are a DL elite. CO will let you either standby for free or do "confirmed standby" in some cases for $25. But pretty much any time the confirmed standby option is available there is a very good chance of making the standby list anyways, unless something happens to a previous flight in the interim.

You are EUA eligable on the CO flights as a KL elite, I believe, as part of the NW arrangement, but I'm not 100% on that.

CO allows same-day standby for free, or confirmed within 3 hours of the new flight for $25.

Note: to get the "free" standby, you need to go to the gate. If you ask a ticket agent at check-in, they're going to push the $25 option. I did do the $25 option once, I was trying to leave about 12 hours early... tried first to switch to a NW flight, found out that it was oversold and they were going to re-accommodate on the CO flight (which had 3 seats left). I called CO immediately and got one of the last few seats for $25. I don't believe I would have made the flight if I had done the "free" standby.

I think thats correct

It is not. Upgrades only apply on NW flights, not on those operated by CO (and only if you do not reside in the US or Mexico).

I have certainly been upgraded in the past on CO, and also with a companion too... who had never flown CO before, and was certainly not elite anything !

Sorry you were asked to pay, an obvious agent error. If your flight is delayed over an hour, DL will waive all fees to accomadate you on the next available flt. Even another airport is an option at no additional cost as long as the new airport is within a 100 mile radius of the original destination.

There is no EUA on CO for FB Plat.

NW will allow you to do standby for another flight on the same day w/o any charge. Check with the folks in the WC, they will be more than happy to help you. Confirmed same day changes are $25, you can do this online with NW.
