Hi there, I have a $150 ECERT under the old 016 system, that is due to expire on 2/17. In the past ( pre merger ) I was able to book a flight thru the end of the current month of expiry ( February ) and travel at a later date ( a few months later ). Has any one have any experience of late? Would like to know how UA has been dealing with this. I have not called yet ( would like to get some advice first ) Thanks and Safe Travels
