Personally, I wouldn't trust the airline to know, or spend the frustrating number of cycles needed to track down the information. I'd also build in some contingency even *if* you determine they supposedly have charging ports - especially if you can do this at a moderately low cost and wind up with something that's handy to have outside of just this one trip

I'd highly recommend anything made by Anker, terrific engineering, support, always highly reviewed. This is a terrific option that strikes a balance between price, portability and power output:
Anker PowerCore 10000 Portable Charger, One of The Smallest and Lightest 10000mAh Power Bank, Ultra-Compact Battery Pack, High-Speed Charging Technology Phone Charger for iPhone, Samsung and More.
www.amazon.com
10,000mAh
Less than 3" x 4" x 1"
$29
Given an iPod Touch (at least the current gen) is 1043mAh, account for charge efficiency, etc., that's about 7-8 full recharges from that tiny little device
