I often did do this when I used to fly more often domestically, but it tends to cause other issues -- the primary one being a "frequent-flyer/mileage account name mismatch" which means that I have to undertake some manual process to collect my miles. I've lost out on countless 'airline miles' as a result via forgetting to do the manual process within N days after the trip. Similarly, automated check-in kiosks are then usually unable to find the reservation via credit-card or passport scan -- meaning you're back to looking up the reservation code, and even that often fails, as if the apostrophe just flat-out causes issues with the query/lookup or something. It can be very frustrating, and I'm increasingly often impressed (and vocalize the same) when I spell my name and the agent enters it correctly AND the system flawlessly handles it, too! The DMV systems in my state are one such example where I used to have issues but, in recent years, the problem appears to have been wholly addressed/handled.
