Has anyone here even flown standard class with Monarch airways to Florida?

We are possibly looking to holiday in Florida in late August and have been checking flights recently. We are limited with Airlines if we want to fly direct from Newcastle and it's normally quite expensive but have come across what looks to be a really good deal with Monarch.

Flights are roughly £440 per person return flying on 28th August but its standard class only - I know that there is less baggae allowance but wondered whether anyone knew whether there was a lot of difference in cabin space or anything else. Premium class flights are approx £200 pp more expensive.

Any replies appeciated.
