Just asking if you are flying from Stansted to Biarritz, I did in 2019 with RyanAir. It all worked well for me and then I got a shared taxi with Express Bourricot to get to SJPdP. If you are staying at Hampton by Hilton Hotel at Stansted don't rely on their wake-up call being on time - the breakfast is pretty bad as well. I am hoping to do another one next year. Good luck from Harrogate.
