Currently, it is only possible to book bundles in the app when the hotel dates match the arrival and departure dates of your flight.
If you want to book a bundle, but only require a hotel for part of your stay, please visit our website. All flight + hotel bundles booked on our mobile or desktop website are available for viewing in the app.
