We've always used the twilight check in at Gatwick. However, this next trip, we have to leave from Manchester and they don't do a twilight check in.

So, I thought OLCI may be an option. I have a few questions...

What information do I need to do OLCI?
My plane leaves at 1.30pm....does this mean I can check in 1.30pm the previous day? (this is what I'm hoping as we will be setting off from home by car for the airport about 2pm the previous day)
If OLCI works....do I just turn up the next day at the airport for baggage drop or can you do this the evening before?

Any hints and tips appreciated
