My grandmother was diagnosed with the early stage of lung cancer and enphazema (shocker: she's a smoker). She is due to have surgery to remove part of one of her lobes next week. My question is, I am planning my wedding (I live in California and she lives in Texas) and need to know if she can travel by airplane? I'm afraid that the recirculated air will be bad for her health. If traveling is going to be a problem for her, I will gladly have my wedding in Texas. Any ideas?
