Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Example Input: Flights out of London Heathrow do not contain departure gate information until about 45 minutes before the flight is ready to depart (presumably so you spend more money at the duty-free). Are there any public APIs or resources that will tell me which gate my flight departs from before the Heathrow departure screens do?

Example Output: Determine gate for departing Heathrow flight

Example Input: When landing at night on most planes they say that due to safety regulations the lights will be dimmed and if you want to continue reading you can use your overhead lamp(it could be that this only happens in Europe I am not sure). I wonder what is the reason for this? What safety does dimming the lights add?

Example Output: Why are plane lights dimmed before landing at night?

Example Input: I am moving to Poland this summer and would like to take my two HEPA air filters with me (it really helps with my breathing, especially when the air is so polluted in the region). However, they are rated for 120V at 60Hz while the only reasonably priced transformers change the voltage to ~120V, 50Hz. I am not sure what else to do because I have have severe breathing issues and even my skin reacts to something there (hard to figure out what this is). A 50 to 60Hz transformer would be more expensive than ordering a new filter from the UK (I can't seem to find these filters anywhere in Europe except on amazon.co.uk), which I would like to avoid doing. 


  Will a ~50W motor (120V, 60Hz) accept 120V, 50Hz power without issue, especially since this is in a fan, which ought to keep it cool? 


Example Output:
Can a 60Hz fan motor run on 50Hz?
