How do you remove the transit time from USPS shipping methods?

Question

Shipping quote from USPS display something like:

Priority Mail 1-Day $6.60

What's the proper way to change that so it only displays as "Priority Mail"?

Answer 1

We were having the same issue with USPS so we made a module that overrides the _filterServiceName() function. This allows us to get rid of any "number of days" type info, with the ability to change it per-store from the Admin, and no need to manually add each "translation" like the other answer suggests.

        if( !Mage::getStoreConfig('carriers/usps/show_number_of_days') )
            $name = preg_replace('/\s+?\d+-day/i', '', $name); // Trim out the number of days, and an optional leading space.

Answer 2

The answer is in: override USPS shipping method name.

make a copy of app/code/core/Mage/Sales/Model/Quote/Address/Rate.php to app/code/community/Mage/Sales/Model/Quote/Address/Rate.php

then replace

->setMethodTitle($rate->getMethodTitle())

with

->setMethodTitle(Mage::helper('shipping')->__($rate->getMethodTitle()))

And add appropriate translations into the Mage_Shipping.csv file.

H/T Amasty for the answer.

note that I couldn't get this to work in 1.6.2, but it works fine in 1.9.0.1
