Going home airport etiquette

[ReasonablySane]

I recently flew overseas to meet a friend (short-haul city break) in her country. She met me at the hotel we were staying in and we had an overindulgent amazing first night (2am) and a very quiet second one (in bed by 10:30). We aren't as young as we once were.

Having had an early night, was it too much for me to expect that we would do something on the morning/lunch of the day I was due to fly home? She knew that my flight wasn't until the afternoon yet left straight after breakfast and made it home to her family by lunchtime. I know this because she texted me.

I made it home to my family at 7pm having spent most of the day on my own. Had I known this was her plan i would have booked an earlier flight. I can't help but feel miffed. AIBU?

I agree it seems you HAD arranged to spend at least half the day with her but she flaked, and as you had flown over to see her specifically I would expect she'd be with you until you needed to get to the airport.

I live in a tourist resort and host lots of visitors....its absolutely draining. I also have to work and look after my family . I know you're friend stayed at the hotel with you but she was away for 2 nights and may well of had things to do at home - it wasn't her holiday - it was yours

I wouldn't do it to a friend who had visited me. Even without them flying to see me, if they're train/bus isn't due then I hang out with them until it's time. I wouldn't leave them in the city that's pretty awful to be honest.

Thank you to everyone who took time to comment. It certainly seems there are two schools of thought on the topic. I know which one I fall into. Sadly, it seems that my friend is in the other!
