Dear WHBM,
Thank you so much for the link to "Richard's Stansted Airport website", I found it very helpful to actually see what flight punctuality is like arriving into the airport. I will definately spend more time scanning the other links available too....I may actually have this all worked out by the time June arrives,...lol.
As for the already purchased Ryanair tickets, I know I can exchange them, however, I believe I paid less than £15 (the exchange fee) per o/w ticket, so it may not be worthwhile,...unless we exchange r/t....hmmmm. Something else to look into
I'm glad to hear more positive input from another experienced traveler regarding AirNZ, as this will be my first travel with them. I can't thank you enough for your continued assistance,...it is greatly appreciated

Sincerely,
Valencia
