Can I fly to France while I send my passport for renewal?
It depends of what country you are travelling from. If you are travelling from a country within the Shengen area, you probably wont be checked at the border but you will be requested a national ID card by the airline company if your are travelling by air. If you are travelling from another EU country but non-Shengen member then a national ID card would be enough for both the airline company and immigration control. However if you are entering France from a non - EU and non-Shengen country, you will most likely be asked for a full valid passport at the immigration control. Hope that helps!
