I have to fly - cooler and other questions

Stuckinthemiddle

I have a three day business trip to take the second week of July.  I am looking for a small cooler to bring my milk back with on the plane.  I was hoping to find something small, yet with wheels and an arm strap.  

Does anyone have a cooler they can suggest?

 Any tips for those who have flown with breast milk and a pump? 

Thanks for any advice you ladies have!
