Ok- simple version. I was scheduled to fly Monday to CUN from DTW via EWR and return Friday on flights from CUN-IAH-DTW. I used miles to upgrade my return flights as I always end up sunburned and grumpy and prefer to have the extra space in 1st.

So, today I found I MIGHT have to leave Saturday. I also received an Elite Notification from CO saying I had been upgraded on the EWR-CUN flight. Very good news, but it seems to be getting in my way.

I went to continental.com and changed the 1st flights to Saturday-2 days earlier. I went, checked the appropriate box for a changed flight and it brought me to a page where it had reward alternatives in front of the flights available instead of the fare. I can see what flight I want, but NOT the amount it costs. Instead I see info on saver passes vs. easy passes, which I have no idea how to change.

Is it not possible to change your flight online once a segment has been upgraded? I know, I know, call the Elite desk. But shouldn't we at least have the OPTION to do it online? I LOVE CO so no flaming me, I JUST wanted to know if it is possible to change flights online if one or more segments has been upgraded. Thanks!

I have NEVER been successful in changing flights on co.com and I do it a fair amount. I always end up having to call the elite line. I had the issue today - I needed to change outbound and return; however after putting in the new date for both - it only changed my outbound and kept my return 6 days earlier so another call to the elite line; the agent I had was very helpful and quickly made my return change. I've had Y or A fares and it changes it to lowest available; therefore putting me in the back. So another call. I am unsure why this glitch has not been fixed; but I have yet to make it work online. Good luck and try the new 75 sunscreen

Changing flights on CO.com is hit and miss with majority of the time a miss. Sometimes you get the price and other times you don't. Just when you think it will go all the way through and complete the change it shows an error message. Unless I want to play around, I wind up just calling the elite desk and it's done.

I would suggest the (paraphrased) Nancy Reagan approach:

JUST DON'T TRY IT!!!

I changed dates and destinations for a flight that I took last month. All looked fine (I was even upgraded five days out) until I tried online checkin...no option to check in. Hmmmmm.

Turns out that the system had never ticketed the reservation, and it took over an hour and multiple supervisor contacts by the phone agent to get the ticket done. They even had to ask me what I thought the fare was, since the system didn't have it!!! (I said 40 bucks, but they didn't buy it).

What a near nightmare. The agent said that I should ALWAYS call an agent in the future if I need to change flights.

in about 85% of the times I have had the same issue, I know sure enough that if I dont get a new ticket in the next few hours or if the receipt doesn't show the change fee (even if the itinerary is correct) then we have a huge problem

this is of course a huge disaster for people who dont know this and head to the airport thinking all is 'ready to go' while its not and then...........

I thought so. Thanks for reaffirming- it was hard to figure out just why it didn't work!

I was thanking my lucky stars that I had tried to check in on line. I bet that I wouldn't have made my flight if I had assumed that all was well. My error was in not noticing the lack of a confirmation email. Online all looked well...

I used to have a lot of problems with changing CO itineraries online, but for the last couple of years it's worked fine about 95% of the time.

I just tried to change my flights for tomorrow. I'm on a paid, domestic ticket. But continental.com is convinced I'm on an award ticket, so it's only looking for award seats. What a pain!

I've tried to change flights numerous times. I have NEVER EVER been successful at all. I get error messages and a bunch of other problems.

I've also had a lot of problems trying to change flights on co.com -- works occasionally, but mostly not.

One question: Say you book a deep-discount fare on co.com. You then call the elite line to change it later, and rebook to the same fare class on another day. Do you get 50% or 100% EQMs?

If you use the elite line and they actually complete a booking for a deep-discount bucket then the reservation will lose its onlineliness. If you use the co.com helpdesk it should remain an "online" reservation.

When this happens I just email OnePass and its fixed (100% EQMs) in 7-10 days.
