I would like to ask if you still call to confirm whether the guest has arrived safely after seeing him off from the airport.

I think we should confirm, but based on the principle of not disturbing the guests, I estimate when the guests will arrive home. If it is not late when they arrive home and it does not prevent the guests from resting, you can make a phone call and express simple concern. Don't be too wordy when greeting. This is also required by basic etiquette. If it is too late, or it is time for dinner, and you are afraid that guests will pick you up for dinner, just send a simple text message to ask. In addition, whether you send text messages or make phone calls, you must be concise, otherwise it will have the opposite effect and make people annoying, so use moderation!
