2) Can I drop off my luggage the day before I fly?

TUI flights
Yes - if you're flying with TUI from Gatwick, Manchester or Birmingham, and your scheduled flight departs during the morning, you can drop off your luggage from 12.00 midday to 10pm the day before you fly. 
When you drop off your bags, you'll need to show your boarding passes at the desk. If you're checking in online, you'll need to print each boarding pass clearly on an individual piece of A4 paper. 
Visit Flight Extras to check in online and print your boarding passes. Please contact us if you're having problems with checking in online within 7 days. If you can't print your boarding passes, you can collect them from any TUI Holiday Store, or from the TUI bag drop desk when you arrive at the airport. 

Unfortunately, due to changes to US security measures, we're unable to offer day before check-in for TUI flights from Birmingham, Gatwick or Manchester to Sanford, Florida. However, we've organised dedicated check in areas which will open a minimum of three hours prior to departure for these flights at these airports.
Cruise holidays
Unfortunately, Day Before Bag Drop is not available for Marella Cruises.  This is due to luggage and medical screening requirements.
The day before you fly
Only one person from your party needs to go to check-in, providing all passengers are travelling on the same booking. They'll need to bring passports, e-tickets, printed boarding passes, and luggage for everyone on the booking, and must be able to vouch for the contents of the luggage. They'll receive luggage receipts and can then leave the airport.
Travelling to Cuba or Mexico? If you're going to one of these destinations, you'll be able to drop off your bags the day before, but you'll need to return to the Bag Drop desk on your day of departure to complete some extra security checks. You'll then be given your boarding passes.
The day you fly
If you want to check in any more bags, you'll need to return to the Bag Drop desk.
If you've already got your boarding pass - go straight to airport security. All passengers must have their individual boarding passes before going through security to the departure lounge. Make sure you reach the departure gate at least 1 hour before your flight is due to leave.
