It usually depends on the time of day for me, the airport I'm flying from and the flight I'll be taking.
When I go next week, I'm flying at 5:45am with hand luggage only (first time ever going abroad without a checked-in hold suitcase!), so I'll be arriving to the airport later than I normally would. I'm already checked in and I've got my boarding passes, so it'll be straight up through security and hopefully straight onto the plane. Not going to bother with breakfast as the flight time is just under 2 hours so it should still be quite early to have breakfast when I land.
Usually if its an early morning flight, I'll stay at an airport hotel the night before, then once I've checked my bags in, I'll have a wander through duty free to get some new aftershave, go somewhere for breakfast and the infamous airport pint (maybe a pint of vodka for me though).
If it's a late morning or afternoon flight, I usually just drive to the airport in the morning and I'll have booked the lounge at the airport so we can just chill, have something to eat and have some drinks. You usually get drinks tokens to use, the last time I went it was 4 each, so it was great. And of course, you can help yourself to as much food as you like. Of course, stopping at duty free on the way to the lounge too.
I rarely take a flight out to somewhere at night, I can't remember the last time I got a flight out that was after 2pm to be honest. When I go to Turkey next year, I'm flying out at 3:10pm, so I'm sure I'll book the lounge for that.
On the way home, it's slightly different as you try to get your bearings in the airport, sometimes the service is a bit slower too... but then I'd just find somewhere to sit and eat, or have a look at the shops.
