Hi Dennis
From your reply, I can't tell if you picked up on the humour (sarcasm?) of the reply from
@Tincatinker If you did, yours was a perfect response. And, in any case, a gracious one.
Lots of people on the forum ask questions which seem a bit obvious to others and/or are not possible to answer. But I'll give it a try. I can't think of any reason for you to favour or compare the second week of September over the third. September is a popular time on the most travelled routes. There will be pilgrims in both weeks. Albergues and cafes will be open. People often ask about weather on the forum - but it's impossible to predict the weather in September 2024, let alone the second vs third week. September is popular for a reason, and one of those is the weather -
usually neither too hot nor too cold, nor too wet. But who knows.
Also, you can find plenty of information on the forum about the route you want to walk. Spend some time browsing and using the search function.
I'm only adding my comments as you are looking around for airfares. I recommend you don't be concerned about whether it's the second or the third week, just take the dates and deal that suit you best
Best wishes
