Aetna vs BCBSIL

 I have BCBS-IL, I've read that they are the hardest to get approval from. My hubby  has AETNA...I went online this morning and looked their WLS policy up. For Lapband it says you only have to have 3 months in a medically supervised program! So my questions are: Has anyone found that to be true????  Which insurance company is easier to get approval from? TIA

I would say Aetna but read the policy and make sure you understand both of them word for word
