Title: How should I hand solder this part?

It has just a slight open end on the sides, but is mostly pad on bottom.  I've got the pads in my package on the pcb accessible on the top and bottom.  Should I just apply some flux, put it on the pcb first, then try to solder hoping it will wick into place?   Or should I presolder the pads with a small bubble, then flux, then place, then head the pad to melt the solder?  Other ideas?

Hot air and solder paste ( siringer one ) we will solder this very easy

I prefer to go the iron route - any thoughts on that?

Don't go iron route if the pads are on the bottom. Buy a shitty temperature controlled hot air station of ebay they wont cost you anything.

If the pads on the PCB are large enough that are not completely covered with a part, there is no issue to solder it with a soldering iron.

If you have solder paste, apply a bit of paste to the pads, stick the component on the board and touch the iron to the sides of the pads until the paste melts.
I've done this before when I didn't want to unleash the full power of the hot air station.

The solder will wick under the part just fine if you have exposed pad you can get the iron on and use some flux.

If you don't have solder paste or hot air: Tin the PCB pads, and the parts pads but only with a very small coating, then flux on both and heat up each pad in turn.  If there's too much solder it won't sit flat. 
If you have hot air: do the above but gentle heat the PCB until the solder on the pad gets a tad shiner - put the part in place and heat that - surface tension will move it into position once the solder on the part and the PCB have melted.
