First Class Mail from my bank headquartered in Cleveland

 The letter is dated 15 May, found in my mailbox here in Sakon Nakhon Thailand on 1 September. 
That is 109 Days

When I airmail a letter from Sakon Nakhon at 70 baht, it arrives at it's U.S. destination within seven 7 Days

Noteworthy: ManyU.S. government offices, such as the IRS, also use the snail mail  through Europe version
