Have you ever heard about "dynamic pricing" with airfare?
We just bought open jaw British Airways-Iberia tickets from YVR-OPO, FAO-YVR.
We found the tickets on skyscanner which directed us to book on Expedia which quoted about CAD$1350 (basic, non-refundable and no checked bag) and CAD$1450 (no fee changeable with no fee and one free checked bag). There are several couples in our group and we needed to book simultaneously to make sure we are all on the same flight.
We tracked the prices for several weeks and we finally got together on a Saturday to book. When we all logged on to Expedia, it initially gave the same prices as before. But when we went to pay, Expedia gave us a message that the price had jumped $100 pp. I was so put off by this because the price had been stable for weeks.
One of the others said we may have been subjected to dynamic pricing. Booking on the weekends may have resulted in higher prices because lots of other people are also shopping for airfare on weekends. Also all the price checking that we did from the same location may have also resulted in higher prices, although I have always thought that was debunked. Anyways, we did decided to clear our cookies (it can't hurt) and wait until Monday.
Meanwhile, on Sunday, I telephoned British Airways. The particular combination of flights that we were looking at was never available on their website. I could never understand how Expedia could offer it when BA did not.
I spoke with a BA representative who explained to me that that particular combination of flights would have to be done manually on their BA booking system, which he did to give me a quote. BA's quote was even more expensive then Expedia.
I asked him why the price cost more than Expedia. He told me that it all has to do with dynamic pricing and that the price changes with supply and demand. So I decided to wait.
On Monday, when we went back to Expedia, the price increase was only $50. We decided to book anyways at $1400 because we had to start booking our accommodations.
A week later, when I checked on Expedia again, the same airfare was still available and the price had dropped back to about CAD$1350.
We waited until Monday and checked Expedia again. Once again, when we logged in it gave us the same price.
PS. FWIW, we booked 6 months out. It was only after we booked that it occurred to us that we are flying out on 9/11. Perhaps that would explain why that particular date was a bit cheaper than the days before or after.
