Good info DD,
I had a feeling the airlines were doing that with the cookies. Grrrrrrrr....
I would get the air fare price. Then I would check again a second or maybe even a third time, after confirming plan's with others in the group... Price would go up. Hard to explain to a people why the airfare would go up in a few hours on the weekend. I always thought it was from the airline selling certain seats at a certain price then running out of those seats. Learn something new everyday.
Should make that a
sticky:
Airlines tracking cookies and how it effects pricing.
Well, that too does happen. Weekends are the worse time to shop for tickets with mid-week generally the best - especially the wee hours after inventories are replenished with seats canceled within the 24 hours buy&think period, etc - but cookies: yep! I first thot it was odd that I have the fare go up on me while shopping the airline site, but then when I tried Sidestep - it found the lower fare on the same airline
and then linked me to the itinerary at the lower fare on the airline's own site! 
So, I tried clearing that airline's cookies, a skill I had to google & learn, and Ta-Dah! Busted!
Thanks a bunch. We were gifted a time share week at El Cid-La Ceiba and the dates are fixed. Perhaps if we flew out a day early. I'll look around some more.
Ah ha! One more reason why time shares are a lousy buy; I cannot bring myself to use the word
investment! Yeah, Fridays are a little cheaper, Thursday cheaper yet - but if you have the TS from Saturday to Saturday, I can see why you'd want to make the free room work, without staying elsewhere for a night or two, etc.
Looking again this morning, as fares & inventories fluctuate, as do my skills, :blush: and based on that info - I think I'd jump on one of these two...!

These flights in/out of Cancun are available Saturday or Sunday, and they're the same planes as the airlines are code-sharing and merging. Arriving Saturday at 6pm, clear immigration & customs, board a reserved van by 7:30pm, be in PDC by 8:30pm, 9pm ferry, 10pm Coz, 10:30pm finally at El Cid. I did that ferry in March after leaving my house at 2:30am and spending half a day in Cancun with a dentist, but I still made the 8am dive boat. Returning would require the night before in a Cancun airport hotel, tho.

Or this is available 3/13-3/21. Same arrival, but leave Coz on Sunday on the 5am ferry if you can stay an extra night there, PDC at 6am, reserved to CUN at 7am - if nothing goes wrong, cool! If things go wrong, Trip Ins! Or for maximum safety, use the TS for Saturday to Saturday, Cancun hotel on Saturday night, still take the 10am plane Sunday. You could use a cheaper hotel in town.
Hey, hope I helped some, and good luck on tying it down @ $300 each...!
