Budget Travel - Does any carrier allow multi-day stops?

Hi forum experts,
My wife and daughter want to visit NYC and then fly on to Europe. I can get them from my city (PDX) to NYC for about $600 RT for the 2 of them (in late June), via Alaska Airlines (and a 2-for-1 ticket). They'd like to stay there and then go on to *somewhere* (anywhere) in Europe for a week.
Any advice on how to go about this? Are there any domestic airlines that offer a "stopover" on the way to Europe? I know award travel allows this but I only have United and NYC is not a gateway for them and, besides, forget about finding 2 award tickets on them! :(
Any advice?
Thanks in advance!!

Most of the airlines I deal with have that facility - some offer it as part of a package (like Icelandair) which includes a hotel, others will give you it as a "multi-city" or "open Jaw"

Many airlines allow you to book either one stopover or an open jaw (leaving for home from a different airport than the one you landed at) on a ticket, but not both. Generally these have to be booked by calling on the phone and can't be done online.

you may also want to look for flights with overnight layovers.

BA allows up to 6 separate legs to be booked at one time

Thanks for the replies.

Actually, I don't see how what I'm trying to do (multi day stop in NYC) qualifies as an open jaw ticket. And a flight with an overnight layover doesn't cut it (we want multiple nights in NY).

I wonder if this is one of those cases where I'll actually need to use a travel agent. Haven't done that in years... :p

But a multi-city ticket does allow that. If you look at my BA example - for example - you see that you can book tickets for flights several days apart and you don't even have to leave from the same airport (or even city) that you arrived at.

AA website allows the same (though only 4 flights) and I can't see why the other US operators won't allow the same

Thanks, Alan. I'll give it a shot!

Arranging a stop-over, especially in NYC, should not be difficult. However, finding decent fares in June might be.

In March you can do the whole thing PDX-NYC-Europe-PDX for $600-$700. In June probably twice that.

Sure, the website will let you book it, but the problem will be the fare class. As soon as you introduce a stopover, you find you're up to the more expensive fare classes. The length of the stopover usually doesn't matter, once it's a stopover, you're moved up to a high fare class.

I think you will come out ahead buying the RT tix you found to NYC and then separately booking a NYC-Europe RT, you'll just have to change planes in NYC on your way back.

I doubt this would be cheaper but it is best to check all options before buying.

A significant disadvantage of two separate tickets is that if one of the flights is delayed or cancelled, your connection is not protected. The airline's contract is to get you to NYC and if you miss your flight to Europe (or back to West Coast), well that's your problem. You could end up losing the money already paid, and have to buy a new ticket at the last minute prices.

a suggestion would to book your flight the next day or make a longer layover to guarantee your connection? i think most europe-ny flights arrive in the morning? so book a flight to pdx that leaves in the evening. Jetblue has a n/s flight to PDX as well as DL
