Same trip, 3 different prices!!!!

I am absolutely shocked at how Virgin Atlantic, Virgin Flying Club and Virgin Holidays can charge 3 different prices for exactly the same trip.
Virgin Atlantic (without signing in to my account) is the cheapest, then Virgin Holidays and finally Virgin Flying Club the most expensive.
How is this???

How much time elapsed between searches?

Their pricing algorithm will be governed by demand, and will change accordingly. It could be as simple as a small bump between fare buckets or something slightly more complicated depending on the room allocations that they are given from the Cosmo.

Give it a half hour and search again, this time in reverse order.. FC, VH and then VS (without logging in) ... The results may be different

The dates of travel are also different... an oversight I guess, but it will have an effect on the price quoted.

Yes, the third one is for 7 nights not 5 which would explain the £300-odd price difference, particularly as the extra 2 nights are a Friday & Saturday, which are always the most expensive nights in Vegas hotels.

So sorry, my mistake.
I see that the 3rd price is indeed for 7 nights, so the Virgin Atlantic page is the same with/without login to Flying Club.
So just a few £££ difference between VH and VA.
Is it because the two separate companies thing ???.
I would have thought the VH would have been the cheaper one.
And the Saturday night rule doesn't come into play when booking a hotel.

Hard to tell where the difference is without seeing the exact price breakdowns, but as I eluded to in my first post it could be a simple fare bucket difference or something to do with how the hotel is priced for inventory control.

My best guess would be that VS have quoted your ticket in a lower fare bucket than VH, a letter that is likely not available to the VH system.

Sorry I can't be of more help.

I am sure that is it Joeyc
Many thanks anyway.

For the first and second pictures (VS against VH), check for smaller things like whether transfers are included or mealplans.
I've had this before with a Dubai trip last year even VS flight + hotel was £200 less than VH but had no car transfers.
That may explain your difference!

Always remember to do seperate searches in Incognito mode. Companies often use your cookies to see that you have been searching for certain things and will adjust prices accordingly.

It doesn't happen as much now, but it is still possible to save a little bit of money by ommitting your cookies.

Thank for all the comments.
Found a very good price with VH for 10 nights flying LHR - LAS ED, returning from LAS-LHR in Premium with the first of those 10 nights staying at the Cosmo then hiring a car and booking a hotel in LA independently.
Have to drive back to and fly home from LAS as LAX was £1585 more.
Had to phone VH to book but the agent was super friendly and helpful.
Very excited.
Our 3rd VH in 12 months.
lol

Great stuff. Have a lovely time.

Many thanks SlimpyJones
