Last year I used cheap tickets.com to get a great deal to Vegas...

This year I went directly to Southwest.com and booked directly from them..I dont know where you are flying out of.. but if Southwest is one of your airport carriers..i would def. check them out.....They seem to have the best prices going..I booked in Dec. for My March trip....$237.ea. RT also Non Stop which is a first for us coming out of Bradley International( BDL) in CT. First I would go to my closest airport's website to see who flys to Vegas..Then go to the airlines website from there...Good Luck.....

ali123- One thing to consider is checking the airline carriers on Tues, Wed, Thurs- some carriers run their internet special or lower fares then. Like other posters mentioned, I also use Southwest. If they fly out of an airport near you, give them a try. They have a non-stop that we use that works out great and their fares have been consistently lower than any other carriers for the dates I need.(for one trip 2 r/t on SW cost less than one r/t on jetblue for nearly identical times.)

SW also has a program you can download to your computer called DING- it posts specials throughout the day that you must book by a certain time that day(usually posted for a few hours)-the fares are sometimes unbelievably low if you can work it into your plans.

Using cheaptickets is another option, but I don't know if you can get a credit if the fare should come down. SW does allow you to rebook if the fare comes down with no change fee and the credit can be used for a year. I think Jetblue does the same.

Sometimes checking the different travel sites is a good starting point, but then you should check directly against the carriers site as they sometimes have lower fares if you book directly-(this happened to me twice with other trips-yes I do actually go to places other than Vegas-LOL)

Good luck! jan

I have to agree w/ Lulu - www.kayak.com is my current favorite site also. I used it about a week ago to book a flight for early March. I just kept checking it daily. Purchased a ticket late on a Friday night and by Saturday morning it had gone up $120. Good luck.

Do the prices vary from day to day on Kayak? If you see a good fare and then don't see it, is there a chance it will come back again.

Fares come and go - you never know if it will or won't come back- I have waited an hour while trying to contact a traveling companion and found a fare gone never to return and in other cases let a good fare go and was amazed to find it back at another time or even lower.. There is no way to be sure that I know of- a very few airlines I use have a 24 hr hold for a fare you like, but I haven't looked for it lately - Delta used to do that for one.

Also, is Cheap Tickets a reputable firm to book tickets through? I usually contact the airline directly. Cheap Tickets havs a good price, but it is with two different carriers for the round trip flight.

I don't recall you mentioning which airport you need to fly from. The only airline that doesn't list on Kayak is Southwest and they often have great fares from the places they fly. I usually find the best fares Tues- Friday or Mon- Thurs. You really don't want to go to Vegas on a weekend - hotels are twice the cost and there are lines for everything.

When I start looking for airfares I check Southwest and Kayak at least twice a day- have downloaded the Ding feature on Southwest and listen for the ding and try to check kayak at least from time to time at a really off hour - very late on Tuesday night or really early in the AM Wednesday-managed to book Fort Lauderdale - Vegas on American for $229- which I think is really good these days.

check out airfarewatchdog.com several times a day.

Allegiant fares are cheap, but you must book early. Our $79 one way flight started at $69, and is now up to $99. Book it while you can.
