I'm the OP & offering an update here. Thanks to all who offered helpful info & suggestions for websites. Hope I can offer some equally helpful advice to the persons who posted that they're also "novices" at finding bargain travel prices.
My trip is in two weeks (March 10th - 15th) and yesterday I booked my flight & hotel stay, got a good deal for both on Expedia. But first I used websites such as Kayak, Airfarewatchdog, Bingtravel and TripAdvisor which compare prices from multiple travel websites. I tracked airline prices for almost 2 weeks before I booked my flight/hotel stay. I saw firsthand that price patterns were very consistent & learned what days the prices offered were the lowest. I found that the days when prices dropped were consistently mid-week days: Tuesdays, Wednesdays and Thursdays. Then the rest of the week (Friday, Sat, Sunday & Monday) the flight prices jumped back up, sometimes doubling.
For example, last week I was tracking round-trip non-stop flights between my two destinations & on Tues/Wed/Thurs there were many listed with the lowest price being $238. But I delayed booking my flight because was hoping for even lower prices. Then I checked on Friday morning & EVERY nonstop roundtrip had more than DOUBLED in price!
Got a little worred when those higher prices lasted thru the entire weekend & Monday. Luckily, I didn't panic & purchase at that high price or settle for flights w/ layovers that take twice as long to get to my destination (and I hate having to switch planes at the Atlantic airport!) I sayed patient & checked prices again Tuesday morning hoping to see the big price drops I was expecting. Well, at first, early in the morning (8 - 10am) the high prices had stayed the same, hadn't dropped! (thought I was scr*ewed, was muttering "WTF?!) However, just a little while later (after 11am?), I checked again & all these nonstop roundtrips had dropped down by more than half-- from about $478 down to $238!!
So I proceeded to compare different individual travel websites (Orbitz, Travelocity, etc.) & used Expedia to book my flights/hotel when I discovered they gave me the best discount price when adding the exact hotel I wanted to my flight.
I'm glad I was patient yesterday & got a good low-priced deal, but actually I should have been even more patient. Later in the same day, out of curiosity I looked again & found that I could have saved even more since United Airlines was offering the exact SAME nonstop roundtrips as US Airways for $10 less! (WTF?!
) Plus I would have gotten an even lower nightly rate at the same hotel using Expedia again combined with these United flights. Guess I jumped a little TOO quick, got afraid to wait a little longer, turned out I could have saved about $35 for the same flights/hotel stay if I had waited & checked online later in the day on Tuesday. (Hey, I could have added one more night at the hotel-- from 5 nights to 6 nights-- for only $11 more!) Well, I'm not gonna keep regretting that I missed out on an even better deal, certainly not gonna drive myself nuts by continuing to monitor the online prices for this package, better to live and learn. Hope that describing my experiences with all this will be helpful to another travel novice or newbie here (and you can learn from my one big mistake!)
