Er...This is my first time here to ask and maybe this question is not so related to OnePass, but I'm just too curious about the difference between Y class and M or B.

I mean, take round-trip EWR-NRT for example as I checked on co.com, it's something like $4565 for a Y ticket but only $1150 for M, then whoever would buy a Y? Or this is the very reason why passenger w/ a non-Y ticket should pay nearly double miles plus an additional service fee to get upgraded?

I raised this question becuase I might start to fly between NYC and Taipei recently frequently (frequently I mean is merely twice a year, but the point is I might do this for the next four years or more...), and I am very interesting in CO's program. I am just not sure if CO's OnePass would be a good choice. Or is there any other suggestion? Thanks!!

For the actual travel, you'll get the same service. However, a few differences in the fares would be:
-Fare options (maybe refundable, or the fees are different to make changes)
-Different cost to upgrade using copay/miles (as you noted)
-You'll get 150% of the mileage toward elite status for Y/B fares and get 2 elite points. With other non-BusinessFirst fare classes, you'll get a maximum of 100% elite mileage and 1 elite point (to count toward your elite status)

Welcome to FT!

As stated above, there is more flexibility with a Y fare (especially on international routes). There are no upgrade service fees, reduced mileage amounts for upgrades, (usually) refundable fares, (usually) free changes, bonus EQMs, etc. etc.

If there is one seat left on the flight, you will most likely have to buy the Y fare.

Y fares aren't so expensive because mileage upgrades cost less; the upgrades cost less because the fares are so expensive.

Flight to Taipei is very likely on Eva. I am not sure if we can use OP miles to upgrade on Eva. If not, then there is not difference between the booking class. Personally, I would book the flights directly with Eva and book the Evergreen Delux cabin. It is always MUCH cheaper than booking on CO.com. Of course, you run the risk of getting 50% EQM for the domestic segments.

I hope Eva stays with Continental when it moves to * Alliance.

I believe CO stopped giving EQMs for everything but the most expensive fare classes on EVA. So you would be stuck buying the most expensive tickets there also, if you wanted EQM.

No, you can not.
You also run the risk of zero EQMs on the BR flights; very few earn CO EQMs any more.

Someone else mentioned that the last seat on a flight will likely be available only at the Y fare. Other reasons for buying a Y fare might include:

- Advance purchase requirement. Sometimes if you must travel on very short notice, Y is the only coach fare that has no advance purchase requirement, even if seats in M or B are still available.

- Minimum stay requirement. Sometimes, your visit may be so short that you don't meet any of the minimum-stay requirements of discount fares.

In short, there are a great many reasons why passengers book Y fares, but rarely would they do so unless one of the above reasons came into play.

Thank you all, guys!!
Now I have a better understanding of CO's program.
