Our passports were due to expire in June. I sent them off w/no expediting on January 26. Got both of ours back today! No expediting, no extra fees. Very happy. If yours expire soon, I'd send NOW! I am a happy guy! The passport site said 8-11 weeks when I sent them in.
I check mine regularly to avoid what happened to me years ago discovering it expired as i was checking in MIA to SXM. Wasn't something I'd want to go through again.
