As Norah says, it depends how big the airport is. When travelling alone, I am a "last minute-arriver" and only use small airports. I don't know Manchester, but with children and possibly with "increased security" which "they" can spring on us at any time, even I would say, give yourselves 2 hours.
What I always wonder is - what does "gate closes at.. " mean?
As I say, I usually arrive at the very last minute, just in time to be the last to check through the gate. (I hate waiting around) There is nothing which closes at the given time of 30 or 45 minutes before boarding, and nobody looks at their watch and tuts if I breeze along 5 minutes before boarding time.
If I am there any earlier, I wait in a seat until the queue has diminished to nothing.
